Left 4 Dead Soundtrack

Left 4 Dead ' s Soundtrack is composed by Mike Morasky. He was also involved in the soundtrack for Team Fortress 2, another highly successful franchise from Valve.

Music is a big part of the Left 4 Dead experience. It brings suspense to a bad situation, alerts you when something happens, and sends chills down your spine. The music is dynamic and is controlled by Left 4 Dead ' s Director. Most of the music is centered around the experience of the game through the Survivors, though music does play while playing as the Infected.

Left 4 Dead
150px|right Left 4 Dead is the main theme of the game. The noticeable cue in this song reoccurs in many other musical pieces in the game, such as in the Tank themes. This usage of a often-repeated cue in Left 4 Dead ' s soundtrack is similar to how some real-life movies have cues (or leitmotifs) which recur throughout their soundtracks.

Left 4 Dead 2
thumb|left|150px|All five Left 4 Dead 2 menu themes Left 4 Dead 2 uses main menu songs that are in the style of each campaign (Dead Center, Dark Carnival, Swamp Fever, Hard Rain and The Parish) as the 5 main menu themes.

Left 4 Death
thumb|150px|left|Left 4 Death thumb|150px|right|Left 4 Death in Left 4 Dead 2 Left 4 Death plays when you have died as a Survivor. The first twelve seconds of it play if the Survivors have been overwhelmed. When a Survivor other than the player has died, a monotone variant of this song is played. "Left 4 Death" in Left 4 Dead 2 has changed in tone. Left 4 Dead 2 variation's occasionally only plays the last few notes.

Skin on Our Teeth
thumb|150px|left|Skin on Our Teeth (Left 4 Dead) thumb|right|150px|Skin on Our Teeth (Left 4 Dead 2) Skin on Our Teeth plays at the end of every campaign's finale to keep the players on edge when the rescue vehicle has arrived, and the Survivors are attempting to board it while evading the Director's last stand against the Survivors. The theme appears to be a modified section of the Tank theme to set a similar but more urgent mood. The name is wordplay of the well-known idiom "by the skin of one's teeth," meaning "by a narrow margin; barely." The Left 4 Dead 2 "Skin on Our Teeth" has been changed to fit the music theme of Left 4 Dead 2.

Pray for Death
thumb|left|150px thumb|right|150pxPray for Death plays at the beginning of every chapter barring the first one, when the Survivors are gathering their supplies and just about to exit the safe room. The name refers to the horrible situation that they're in and how they would rather die than become Infected. This track was made, having a very constant rhythm, to give a sense of security but also temporary stay, almost like elevator music. Like with much of its music, Left 4 Dead 2's version (Left) uses a banjo theme for the backing track to help tie in with the southern setting. Whereas the original Left 4 Dead (Right) gives a more dark and sinister feel with a slight variety in the tracks for the separate campaigns to fit in with each setting. These all have separate names: No Mercy ― "No Mercy For You"; Death Toll ― "Death's Toll"; Dead Air ― "Dead Air Time"; Blood Harvest ― "Blood Harvestor"

Pray for Passing
thumb|150px|right Pray for Passing plays only at the final chapter, The Port of The Passing campaign, when the Survivors are gathering their supplies and just about to exit the safe room to meet the original Survivors from Left 4 Dead. The name refers to the horrible situation that Bill sacrificed himself from the original group and how the Survivors cope with his passing. It also means on how the original Survivors pass on the "torch" to the new Survivors from Left 4 Dead 2. It features combined music from Left 4 Dead 's No Mercy campaign and Left 4 Dead 2 's "Pray for Death" safe room music.

Deep in the Forest 1 & 2
thumb|150px|rightDeep in the Forest is the name of the saferoom music played only in the new DLC campaign Cold Stream. There are 2 tracks Deep in the forest 1 (which plays in map 2's safe-house) and Deep in the forest 2 (which plays in maps 3 and 4 safe-houses). The name refers to the situation and environment the survivors are in during the Cold Stream maps, as it the campaign is based in a pine forest and reflects the fact they are so alone out there.

The Monsters Without
thumb|150px|left thumb|150px|right The Monsters Without plays at the end of every chapter barring the finale, after the Survivors have reached and closed the safe room door, with statistics being shown and the next chapter loading in Left 4 Dead. The "Monsters Without" in Left 4 Dead 2 has changed.

The Monsters Within
thumb|150px|left thumb|150px|right The Monsters Within plays after one or more of the Survivors have boarded the rescue vehicle and escaped, and throughout the "credits." The Left 4 Dead 2 "The Monsters Within" is very similar to Left 4 Dead, only the music theme is changed.

Gas Can of Victory
thumb|150px|leftGas Can of Victory plays when both teams have the same number of points on a Scavenge map and is used to keep both teams on their feet, as suggested by similarities to the "Skin on Our Teeth" music theme. The name is self-explanatory as it plays during the fight to fill the gas can that would cause the Survivors to claim victory for the round. This song is actually audible in the background during parts of the Tank theme, but it has been edited for Left 4 Dead 2.

Chocolate Helicopter
thumb|150px|leftChocolate Helicopter is the song used in the intro video of Left 4 Dead 2. The name refers to the sarcastic comment Nick makes toward Coach during the trailer.

Horde Struggle

The tune starts off as the music of Blood Harvest as a reference to the presence of the original survivors, then a second theme enters with a strong jazz organ, (referred to as "internal organs" in the game file.) The music is similar to that played at a party or a night club because Rayford is portrayed as a city with a vibrant nightlife.

Cold Stream
thumb|150px|leftThis is the current introductory theme music for the DLC campaign Cold Stream. As of yet it is simply known as Cold Stream. It has a very mystical backing tune and a solemn-like stringed instrument playing the main tune. It reflects the atmosphere of the campaign's lonely pine forest setting, and gives a depressing and apocalyptic feel to the start of the map.

Tank
thumb|150px|left thumb|150px|right thumb|150px|right Tank is the musical cue of the Tank, which plays after the Tank has noticed the Survivors and loops until it has been killed. Normally, Tanks have 2 different themes, one that plays when the Tank has spawned during normal campaign, and one that plays during the finale (shown in the top left). In Dark Carnival, finale Tanks are accompanied by a heavy rock version of the Tank's song to associate with the Midnight Riders theme of the finale. The first song is a play on the song Midnight Ride called Midnight Tank. The second song is a play on the song One Bad Man called One Bad Tank.

Witch
thumb|150px|right Witch is the musical cue of the Witch. The first fourteen seconds of the track loop play as long as the Survivors are in close proximity to the Witch, and from 0:15 to 0:45 is what plays after the Witch has been startled. From 0:45 and on is the music that plays when a witch has incapacitated her victim and is tearing them apart or if the witch has been set on fire.

The Wandering Witch
thumb|150px|left

The sounds that play for the Witch during the daylight. When approaching the Witch 'lost_little_witch' plays, when getting close to the Witch 'loud_angry_little_witch' plays. When startled, it uses the same soundtrack with the original witch soundtrack.

Bride Witch
right|thumb|150px

This song is played when the player is within the Bride Witch's vicinity in the First Chapter of the Passing. It is a variation of the Bridal Chorus (generally known as "Here Comes the Bride" or "Wedding March" in English-speaking countries) mixed with the Witch's standard theme. Similar to the original, it will get louder as the player approaches her.

Bacteria
Bacteria is a name for the Special Infected jingle that plays when one is around (even in spawning mode). They each have their own tune to identify them by. They also have a song that plays when their attacks hit. Every Special Infected's Bacteria have their own select number of notes, and two versions of said notes played on piano and string. However, no Infected has a Bacteria with only one note, seven notes or nine notes. It may be a good idea to know which bacteria music corresponds to which infected, as it gives clues to what kind of Special Infected is going to attack your team (as Survivors) next when distinct growls and noises Special Infected make are inaudible. As of the November 19th patch of Left 4 Dead 2, bacteria sounds have been disabled in Versus in Left 4 Dead 2.

Hunter
thumb|150px|left The Hunter's attack is known as Exenteration. Exenteration is also a medical term for disembowelment, which is fitting as the Hunter claws at your stomach. Its theme has three notes and its the fastest one to go with the speed of the Hunter.

Smoker
thumb|150px|right The Smoker has two musical cues that play when attacking. The one when Survivors are being dragged away is named Tongue Tied, then the song played when fully constricted is called Asphyxiation. Asphyxiation is a term for suffocation, fitting for the Smoker. It consists of two notes.

Boomer
thumb|left|150px The Boomer's attack is known as Pukricide. This term comes from puke and the suffix -icide, making the term mean "To kill by means of vomit." For the Boomer, five notes play.

Charger
thumb|right|150px The Charger has two songs that go along with him. Contusion plays when he grabs a Survivor then Mortification plays as he pounds them into the ground. Contusion is another term for bruise (probably from being slammed by him or referring to the Charger's bruised and rocky right arm) and Mortification can mean either humiliation, or decay of a part of the body, possibly referring to the Charger's shriveled arm. Its theme has six notes and it has been the only theme that has changed, in the Swamp Fever videos from E3 it shows it had only the violin without the trumpets and it was slower but with the same mood.

Spitter
thumb|150px|left The Spitter's song is called Enzymicide. Enzymes are a type of protein that speeds up chemical reactions, and are known to be present in human saliva, while the suffix -icide means to kill. Therefore, the term means "to kill by means of Enzymes". Its theme has four notes.

Jockey
thumb|150px|right The Jockey's song is called Vassalation. The word can be broken into two parts, Vassal and -ation. Vassal means slave, and -ation can be "state of", so the word means "state of being a slave," referring to the players inability to control their own movements. "Vassalation" is also a play on "vacillation", meaning "to waver in course or opinion" or "to sway through lack of equilibrium"; again, referring to the Jockey's effect on the Survivor. It is the longest bacteria at a total of eight notes.

Train to Miami
thumb|150px|left Train to Miami is one of the songs featured in the two commercials for Left 4 Dead. It was created by the hardcore punk/noise rock band Steel Pole Bath Tub, fronted by Mike Morasky, and played in their album The Miracle of Sound in Motion. According to Morasky himself, he was surprised when he found out that the person responsible for creating the commercials decided to use his song.

Grounds for Divorce
thumb|150px|right Grounds for Divorce is one of the songs featured in the two commercials for Left 4 Dead. It was created by English band Elbow, which was a part of their album The Seldom Seen Kid, released in 2007. Lyrics from http://elbow.co.uk/

Jukebox
The following are songs played on the jukebox in the waterfront cafe, in the small cafeteria's jukebox in the plank country, the jukebox in the pool-room in The Underground, and the one inside the house to the left of the bridge in The Port and Port Finale.

Re: Your Brains
thumb|left|150px Re: Your Brains is a song by Jonathan Coulton, also available on the Rock Band Music Store for 80 Microsoft Points. Its chorus (starting after 'You're all gonna die screaming') will attract a horde. The song can also be downloaded from Jonathan Coulton's blog.

The Saints Will Never Come
thumb|150px|right The Saints Will Never Come is a jazzy, Louis Armstrong-like tune, and likely a pun of the song "When the Saints Go Marching In". This song also plays in the background when you start up the Crescendo event in The Quarter.

One Bad Man
thumb|150px|left One Bad Man is a song by the fictional band, Midnight Riders. The riff of the song bears some resemblance with the riff of the song "Seek & Destroy" by the American thrash metal band Metallica and very similar to "Ramshackle Man" by Deep Purple. This song is currently available for download on the Rock Band Network for 80 Microsoft Points.

Midnight Ride
thumb|150px|right Midnight Ride, sometimes known as Midnight Riding, is another song by the fictional band, Midnight Riders. Midnight Ride was also used in a commercial advertising Left 4 Dead 2. This song is currently in playtesting and will be available to download soon on the Rock Band Network.

Save Me Some Sugar (This Won't Take Long)
thumb|150px|left Save Me Some Sugar (This Won't Take Long) is a Midnight Riders song released in The Passing. It can be used to obtain the "Killing Them Swiftly To This Song" achievement. After the first chorus is heard (2:03), the lyrics go "Aw yeah..{gibberish}..Alright". There was a rumor when the gibberish is played backwards, it perceivably can be heard as, "Bill is dead", in reference to the "Paul is dead" legend, and the fact that Bill was the Survivor who canonically died.

All I Want For Christmas (is to kick your ass)
thumb|150px|right All I Want For Christmas (is to kick your ass) is an official song by the Midnight Riders, meant to celebrate the Holidays. It makes various references to Christmas traditions of Santa Claus, The Christmas song "I saw mommy kissing Santa Claus" (the lyrics "You stole my woman" humorously refers to this song.) and Charles Dickens' A Christmas Carol. It also has tune similar to that of La Grange by ZZ Top, whom the Riders strongly resemble. It was released around christmas 2009 but implemented in-game with The Sacrifice.

The song was given an offical backstory on the official Midnight Riders youtube page, "In 1987, the Midnight Riders were asked to participate in a children's charity Christmas album with their rock peers. The Riders refused. In a 1993 Guitar God Magazine article, Dusty explained: "Givin' kids charity just makes 'em weak, man. Teach a kid to fish, he can eat fish his whole life. Teach a kid NOT to fish, he starves to death. Where I come from that's murder, Homes." A few years later, the Riders grudgingly agreed to participate in a 1998 Christmas album in exchange for not having to do 30,000 hours of community service. "All I Want For Christmas is to Kick Your Ass" was written, recorded and mailed in less than one hour."

Still Alive
thumb|150px|left Still Alive is a song by Jonathan Coulton, vocals by Ellen McLain. It is the popular credits song to Portal, another of Valve's games. It stands as the rarest song to play on the jukebox. However the song is played much more frequently on the demo version of Left 4 Dead 2. It appears to have more chances to get played in The Passing. It's possible that this song was put in as a hint for Portal's sequel, Portal 2.
