* [[http://www.youtube.com/watch?v=S68GmenFk2g "One Final Effort"]] from ''Halo 3''.
* [[http://www.youtube.com/watch?v=uczv9V1QsDg To Kill a Demon]], played during one of the more ridiculously fun vehicle sections in ''Halo 3''.
* The [[http://www.youtube.com/watch?v=M0mQk7JEVq4 main theme.]] Now with [[http://www.youtube.com/watch?v=a43xjc6iT9k face-melting guitar solos.]] Or [[http://www.youtube.com/watch?v=JFOJ13sw8o4 a full orchestra and chorus.]]
** And then [[http://www.youtube.com/watch?v=3IzDPgoI8TU Unyielding]] came along to prove this theme did not require any of the above to ROCK.
** And then it got cranked up to eleven by Reclaimer, or "What happens to you take a kickass rock song playing to a battle, remix it, and then play to the second, larger battle immediately afterwards."
* [[http://www.youtube.com/watch?v=Ehd-cihwTKs Earth City]] from ''{{Halo}} 2''.
* The soul-soothing [[http://www.youtube.com/watch?v=iNhfuhiveUM In Amber Clad]] from ''{{Halo}} 2''.
* [[http://www.youtube.com/watch?v=t9P8nJfyC_4 Blow Me Away]] by Breaking Benjamin, used in ''Halo 2'' at the climactic battle scene. After a gameful of sweeping orchestras and choirs, it decided to ROCK OUT.
** That's the equally-impressive vocals version, but [[http://www.youtube.com/watch?v=e1lUwDFsyPw this]] is the version you hear as you're running the gauntlet of, oh, dozens of aliens doing their best to splatter each other into little chunks of goo.
** The best part of that song is how it crops up as you enter the room to a bunch of elites and brutes fighting, and then launches into the insane rock as two hunters join the party. At that point, all ideas of hanging around until the groups destroy each other goes pretty much out the window. (And with that, we have the answer to how to stop the player sitting out of your huge battle scene - invoke AutobotsRockOut.)
** The version including the vocals was also used as the theme tune for Major League Gaming's coverage of their 2006 Halo 2 season.
* [[http://www.youtube.com/watch?v=g40t7coTQ8g "Follow Our Brothers"]], from ''Halo 3''.
* [[http://www.youtube.com/watch?v=_Td9-JRM8Fg "This Is Our Land"]]. Made all the more awesome because that's playing as you are rolling into an invaded human city with every intention of driving those Covenant bastards back out.
** [[http://www.youtube.com/watch?v=bW8nG7n_M3s "This Is The Hour".]] Really, there ''is'' no better music to end the world on.
* [[http://www.youtube.com/watch?v=g1fPUejOTB8 "On A Pale Horse"]], because Banshee fights on the bridges of Assault on the Control Room are always fun.
** ''Halo 3''[='=]s [[http://www.youtube.com/watch?v=aDSQbCYrXu0 version]] topped it, as the first part of the piece "Behold a Pale Horse". A lot of ''Halo 3'''s work were new versions of themes from the first and second.
* [[http://www.youtube.com/watch?v=_Q257zs80k8 "Reborn"]], the overture of the final level of ''Halo 3''.
* [[http://www.youtube.com/watch?v=34cGnonnTiA "Greatest Journey"]], ''the'' most epic ''complete'' rendition of the Halo Theme (''[[http://www.youtube.com/watch?v=M0mQk7JEVq4 Halo]]'' being the original and ''[[http://www.youtube.com/watch?v=awmUc8onlb0 Mjolnir Mix]]'' being the second) serves as the background music for the final [[IncrediblyLamePun run]] of ''Halo 3''.
** [[http://www.youtube.com/watch?v=q_pAa9252Uo A rival for the title of most "complete" rendition.]]
* [[http://www.youtube.com/watch?v=d_EzTOGqLs4 The]] [[http://www.youtube.com/watch?v=jZrhQ-Rtwj4 entire]] [[http://www.youtube.com/watch?v=S68GmenFk2g Covenant]] [[http://www.youtube.com/watch?v=_1hAUE9o-MM suite]] is one big CrowningMomentOfAwesome for Crowning Musics of Awesome.
* [[http://www.youtube.com/watch?v=RO1y7WQfD9c Rock Anthem For Saving the World]]. Awesome track, even more awesome name.
* The main menu theme of ''Halo 3'', [[http://www.youtube.com/watch?v=d7w76B7fO_4 Unforgotten/Never Forget]]. It's really a beautiful piece.
** Probably a TearJerker / AwardBaitSong if there ever was one. "Unforgotten," indeed.
* Now, with ''Halo 3: ODST'', we can add [[http://www.youtube.com/watch?v=IyOezaeH00M Menagerie]] and [[http://www.youtube.com/watch?v=5q-HxbVbuMA Skyline]].
** Menagerie gets special mention for reappearing in ''Halo: Reach'', playing as Noble Six helps escort a certain Gunnery Sergeant while the Covenant glass New Alexandria in the background.
** [[http://www.youtube.com/watch?v=bBeyFxCsoOw Traffic Jam.]] Has a driving rhythm, makes an orchestra sound as awesome as an electric guitar's power chords, and has an actual electric guitar soloing ''on top of that.'' Played during Mickey's mission where you roll through the enclosed city streets of New Mombasa in a Scorpion tank.
* Most of ''Halo Wars'' music tracks are [=CMoA=] in their own right, but the ones that stood out were [[http://www.youtube.com/watch?v=pxOwb6QPgHQ "Spirit of Fire"]] and [[http://www.youtube.com/watch?v=phk7di38iv8 "Insignificantia".]]
** We can also add [[http://www.youtube.com/watch?v=MoHCpa4rG7I Heavy Price Paid]], it's a good song.
* So many from ''Halo 1'':
** [[http://www.youtube.com/watch?v=t97u9qmgwN0 "A Walk in the Woods".]]
** [[http://www.youtube.com/watch?v=3db17gQ8XTs "Ambient Wonder".]]
** [[http://www.youtube.com/watch?v=cr3ViZXl5Ws "The Gun Pointed at the Head of the Universe".]]
** [[http://www.youtube.com/watch?v=L4uVrq9P9kI "Trace Amounts".]]
** [[http://www.youtube.com/watch?v=BSqm5Id6Hw0 "Under Cover of Night".]]
** [[http://www.youtube.com/watch?v=NpOVKbM7vlA "Devils... Monsters..."]]
** [[http://www.youtube.com/watch?v=5fPFtDdqnJI "Covenant Dance".]]
** [[http://www.youtube.com/watch?v=XUF17cd8mKk "The Maw".]]
** [[http://www.youtube.com/watch?v=vLoRT5FKy2o "Drumrun".]]
** [[http://www.youtube.com/watch?v=nqgcaJ0rQDc "The Long Run".]]
** [[http://www.youtube.com/watch?v=RO1y7WQfD9c "Rock Anthem for Saving the World".]]
** [[http://www.youtube.com/watch?v=H20Ok5BKR-Q "Perilous Journey".]]
** The reprise of "Under Cover of Night" going into the final level of ''Halo 3'' is a standout moment from that game. To know that the two biggest badasses of the humans and Elites were about to go to their potential deaths...breathtaking. "We'll head for the Portal...and then we'll all go home."
* The [[http://www.youtube.com/watch?v=pTV5Uf2YZGc Epilogue Suite]] for ''Halo 2''. Those guitar riffs during the first minute especially.
* [[http://www.youtube.com/watch?v=qBADAK3fMxE Wage]] from the Delta Halo Suite. When you listen to it, whatever you are doing becomes epic by association. Putting it with [[http://www.youtube.com/watch?v=EQR-n6Z7Kxk the entire suite]] just takes it {{Up to Eleven}} for bonus points.
* From ''Halo Legends'', [[http://www.youtube.com/watch?v=eScd8oWPCC4 "Machines and Might"]], a short but very sweet tune, heard in the equally sweet short, "Prototype" among other episodes.
-->"Oh my God. It's the Prototype suit."
-->"But who the hell's piloting it?"
** [[http://www.youtube.com/watch?v=3T8g3kOEmYo Sacred Icon Suite 2]] - basically the Arbiter's theme meets Unforgotten meets Sacred Icon Suite 1, except on steroids, on fire, and dual-wielding Rocket Launchers. That's how awesome it is.
* With ''Halo: Reach'', [[http://www.youtube.com/watch?v=ktce1qctRbM ashes]] (a real TearJerker to rival Unforgotten or the ''Halo 3'' remix Never Forget) and the indescribably awesome [[http://www.youtube.com/watch?v=Q_aMWCn_ZDQ Walking Away]].
** [[http://www.youtube.com/watch?v=7mj4uoPxHYs "We Remember"]], which is an awesome combination of Combat Evolved's rock and ''Halo 3'''s choral tunes.
* [[http://www.youtube.com/watch?v=vQJGlhWVaic Finish the Fight]], the music for the ''Halo 3'' Announcement Trailer (which was remixed into ''This Is The Hour'', above), almost tells its own story. The Master Chief's approach is heralded by a chorus, Cortana's appearances by piano, until they meet in the same plane, emphasized by the piano chords of the ''Halo 3'' leitmotif - which is then echoed via OrchestralBombing as the Chief looks up to see a Covenant armada closing in on the New Mombassa portal, as an orchestral rendition of ''Rock Anthem for Saving the World'' pounds at the viewer ... and then, as the portal opens, it shifts into a variation of ''The Last Spartan'', the ''Halo 2'' theme, building to a crescendo as the portal lights up. Then, when Cortana whispers ''"This is the way the world ends,"'' the orchestra answers, ''emphatically'', with the ''Halo 3'' leitmotif, which doesn't evoke annihilation so much as heroism - as if the answer to Cortana is: "No. This is the way the world will be ''saved''." The last reprise of the leitmotif is powerful enough to bring tears to the eyes.
* Technically, it's not [[VideoGame/{{Myth}} originally]] from ''Halo'', but it appears in each game: [[http://www.youtube.com/watch?v=DCFtBlKDIaM Siege of Madrigal]], one of the most forlorn, haunting, and awesome {{Lonely Piano Piece}}s ever. It's pretty much Bungie's official theme. So much so that it continuously loops in the hidden tribute room easter egg on the mission "The Package" in ''HaloReach'', which contains farewell messages to the community. *[[TearJerker SNIFF]]*
* A motion comic of the story The Return, from ''Halo Evolutions'', was recently made. The first bit of music from it, a OneWomanWail piece, is absolutely amazing.
* From ''ODST'', during the final level, you have [[http://www.youtube.com/watch?v=dR7d5PEfVYA Mercy Plea]]. So somber yet heroic; evoking the feeling of soldiers going off to face their final battle with honor.
* From ''Reach'', we have a track that plays during the beginning of Tip of the Spear, and caps off the game credits: [[http://www.youtube.com/watch?v=fYS-ZV_buDI Unreconciled]]. So chillingly ''epic''.
** Also from ''Reach'' is [[spoiler: [[http://www.youtube.com/watch?v=eTRtAB7spno The Pillar of Autumn]]]].
** And [[http://www.youtube.com/watch?v=t_cF8UlwOZE Epilogue]], one of the biggest {{tear jerker}}s of the series, on par with "Heavy Price Paid", "Unforgotten", "Heroes Also Fall", and "Ashes".
** Plus the [[http://youtu.be/3nBj1BlKMzY Lone Wolf variant from the beta]].
* With Halo 4, Neil Davidge proves himself a worthy successor to O'Donnell (who is contracted to Bungie, not 343 Industries), with "[[http://www.youtube.com/watch?v=vqL5eu8DOgI Arrival]]", an epic piece that plays during the final battle of the Campaign.
* On the note of ''Halo 4'', we have the very first title in the soundtrack, [[http://www.youtube.com/watch?v=JtvQ3YtdwMQ "Awakening"]], an ungodly mix of electric guitars, choir, and violins.
* Also, the Infinity's/[=UNSC=]'s {{Leitmotif}} in ''Halo 4'', "[[http://www.youtube.com/watch?v=TmAPACP5nPM To Galaxy]]". A slow build-up leading to a sweeping, heroic, but serious-sounding piece. The build-up section is used as background music for the multiplayer menu, but other segments are used in Spartan Ops and of course, in the [=UNSC=]'s "We are the giants now" BadassBoast intro.
** [[http://www.youtube.com/watch?v=o9IJff64R-U A cover of "To Galaxy"]] by violinist Taylor Davis and pianist Lara de Wit.
* Another awesome ''Halo 4'' track is "[[http://www.youtube.com/watch?v=npMi1Il2n7w Faithless]]", an epic track with a pounding beat that plays while carving through Covenant on Ivanoff Station, and in a few Covenant-themed Spartan Ops missions.
* [[http://youtu.be/aja93GXDsbY Revival]] starts off with an ethereal chant that ends with a surprisingly epic bass drop, and plays when you first meet the Didact to great effect.
* [[http://www.youtube.com/watch?v=B70lpTUyxAA Green and Blue.]] John and Cortana. Earth and sky. Life and sadness. Whatever you read into the title, this song is a powerful, compelling dirge, and it was cut criminally short in the actual game.
** The [[http://www.youtube.com/watch?v=lXjUGO0-0Gg Remix version by KOAN Sound]], while different in style and tempo (and only half the length), is equally beautiful.
* [[http://www.youtube.com/watch?v=kIaYSfZBFTU Arrival]], [[http://www.youtube.com/watch?v=PMYBtjG2WjY Revival]], and [[http://www.youtube.com/watch?v=a4_mZw9bheI Nemesis]] all received top-notch dubstep remixes for ''Halo 4'''s weaponry trailers. "Nemesis" is fast paced, with some epic drops. "Arrival" focuses more on the original's violin work with a new beat, and "Revival" is a bit calmer, focusing more on the original's singing.
* Another two epic pieces are [[http://www.youtube.com/watch?v=AIv2brYUaps Push Through]], which plays when the Chief's driving a tank to clear the Covies attacking the ''Infinity''; and [[http://www.youtube.com/watch?v=RWG5UJdvcnk Convoy]], the thumping track which plays when the Chief boards the Mammoth.
* [[http://www.youtube.com/watch?v=oz5imQdccRQ Armour]], an eclectic electronic mix for the concept art trailer.
* Co-composer Kazuma Jinnouchi created some of the best action themes in the game. Jinnouchi's compositions are much more familiar to ''Halo'' fans than Davidge's atmospheric themes: epic scale, bombastically orchestral and clearly influenced by Marty's works.
** [[http://www.youtube.com/watch?v=2dtO57pH54Y Atonement]], the main menu theme. One section stands out is a powerful build of strings, the climax of which ends with a quiet reprise of [[http://www.youtube.com/watch?v=4vZkWqww0Sk Keep What You Steal]] (more or less Cortana's theme) from ''Halo 3''.
** [[http://www.youtube.com/watch?v=9KFwZLjOc0w Mantis]], which plays [[ExactlyWhatItSaysOnTheTin when you're piloting the Mantis]].
** [[http://www.youtube.com/watch?v=Wqbndr2C4Eo Lasky's Theme]].
** [[http://www.youtube.com/watch?v=DCrL76vGpNA 117]], the Master Chief's {{Leitmotif}}.
** [[http://www.youtube.com/watch?v=iGX1fv4DgaA Sacrifice]], the heroic crescendo played during the Chief's entry into the Didact's ship.
** [[http://www.youtube.com/watch?v=K8PFR3bQ5fs Never Forget]], an excellent remix of a classic Halo composition.
** [[http://www.youtube.com/watch?v=MJTic7iGBa8 Majestic]], the incredible theme song for Spartan Ops.

Marty O'Donnell is god, but Neil Davidge and Kazuma Jinnouchi are worthy successors.
