Metal Gear/Awesome Music

Every single Metal Gear game owes a great deal of its awesomeness to the incredible music.

Metal Gear

 * Even if it doesn't, Enclosure from the first game does. Not to mention the MGS4 remix of said theme.
 * The MGS3 version of the theme.
 * Theme of Tara from the original Metal Gear

Metal Gear 2: Solid Snake

 * The Theme of Solid Snake, from Metal Gear 2 definitely deserves mention.
 * There's also the Integral version, which remixes it with some of Solid's sensibilities.
 * Hell, the entire soundtrack from Metal Gear 2 deserves mention. There is a significant improvement in the quality and complexity of the music, compared to its predecessor - no doubt due in part to the addition of the SCC sound chip, which increased the number of sound channels from 3 to 5.
 * Metal Gear 2's Zanzibar(land) Breeze may only play during the prologue, but with all the remixes that are out there, one might think it was a recurring theme. Some remixes include the remix on the official music collection, and this troper's favorite the Red Disk/Policenauts version.

Metal Gear Solid

 * Metal Gear Solid: Main theme
 * Rex's Lair
 * The original game also gives us The Best is Yet to Come, played at both the beginning and end, and Mantisâ€™ Hymn, an appropriately awesome theme for one of the best boss fights ever.
 * In the original, it was a prelude; the Gamecube remake also used it for the battle.
 * Fan Film Metal Gear Solid Philanthropy adds Will There Be An End, composed specifically for the movie and performed by the same singer who did The Best is Yet to Come.
 * Say what you will about the Twin Snakes remake, but you can't deny that it had a good soundtrack. Check out Soldier vs The Ghost, Assassin vs Saladin, and Snake vs Mantis
 * Also, the original version of "Encounter" stands up surprisingly well, and even got remix made for Super Smash Bros.. Brawl.
 * Don't forget the intense version from the original Metal Gear Online, used for the first part of  in MGS4.
 * This remix of the main themes from MGS and MGS2, SNES style.
 * "Escape" from Metal Gear Solid.
 * Some good examples are its boss themes, such as Soldier vs. Ghost or Intruder vs. Parasite.

Metal Gear Solid: Ghost Babel

 * The final battle against Viper (Ascent) is undoubtedly one of the best boss themes on the GBC.

Metal Gear Solid 2: Sons of Liberty

 * Let's give Metal Gear Solid 2 some love for "Yell Dead Cell" (if that is what it's called). Awesome with an undertone of creepiness that suits the bosses perfectly. Also made it into Smash Bros.
 * MGS2 also has Father and Son, the music for the battle against Solidus.
 * Tanker Incident (especially during the alert phase). Just listen to the alert mode at 2:18 and Olga's battle theme at 6:45 and tell me that's not awesome.
 * The Metal Gear Solid 2 Theme.
 * The ending theme of MGS2.
 * Countdown to Disaster from Metal Gear Solid 2.

Metal Gear Solid 3: Snake Eater

 * Snake Eater, the theme song of Metal Gear Solid 3, managing to be both a parody and a spectacular example of 60s spy tunes.
 * What about "Way To Fall", the ending theme of MGS3 by Starsailor? Easily up there with several of the Silent Hill themes, if not the most fitting ending theme ever for a game.
 * The Debriefing music from Snake Eater, including its Triumphant Reprise of the original MGS theme.

Metal Gear Solid: Portable Ops

 * Calling to the Night, the unexpectedly awesome theme song for Metal Gear Solid: Portable Ops.
 * Also from Portable Ops is Gene's final boss music, an eerily calm and driving song. This one also got orchestrated on the anniversary album.
 * The main theme of Portable Ops, Show Time.

Metal Gear Solid 4: Guns of the Patriots

 * Metal Gear Online - Peace Walker Theme
 * The song "Old Snake" from MGS4 deserves a mention.
 * From MGS4 we shouldn't forget "Desperate Chase", "Metal Gear Saga" and "Crying Wolf", all badass tunes.
 * For another take on "Metal Gear Saga," here's an equally epic remix of it.
 * Not forgetting "Guns of the Patriots."
 * Also not to be forgotten is the awesome song "Infinite Loop," which plays during the battle with RAY.
 * Also Father and Son from MGS4.
 * No love for the Love Theme from MGS4? One of this troper's favorites.
 * The song is repeated when Snake has to . And if you can pay attention to the split screen action, it's incredible sadness is made all the more evident as it seems like.
 * It even made an Early-Bird Cameo: this from Super Smash Bros. Brawl.
 * Here's To You From Metal Gear Solid 4. A perfect heartwarming song to end the series.
 * MGS4's version of Enclosure can be quite a Tear Jerker especially since it plays.
 * Sin, the song that plays during the fight with Vamp. It sounds like something from Turok Evolution, which is not a bad thing.

Metal Gear Solid: Peace Walker

 * Peace Walker: Heaven's Divide.
 * Peace Walker also has the main theme. which is later remixed into Zero Allies! And of course there's Love Deterrence and Koi No Yojushiryou.
 * What makes them more awesome is that, like in past games, they play as certain parts in the game, Heaven's Divide is played in the mentioned part above, while Koi no Yokushiryoku is played . This is a different change of music from past games,
 * The quiet piano version of Snake Eater also qualifies. It's a good callback to the game of the same name, the part of the game where the flashback scenes tend to take place (it plays "Snake Eater" if you take too long), and in general has sort of a wistful, flashbacky feel to it.
