* [[http://www.youtube.com/watch?v=jCt31W7yUUk "9"]], from ''Master of Arena''. Also qualifies as Villain Music. The same music was used in ''Another Age'' and again (with its [[http://www.youtube.com/watch?v=O5zQMjiDrtc remake]]) on ''Nexus''.
* [[http://www.youtube.com/watch?v=CqCA1Udh718 "Shining"]] from ''Nexus''.
* [[http://www.youtube.com/watch?v=Bib1ALjlfNE "Apex in the Circle"]] from ''Master of Arena'', and its [[http://www.youtube.com/watch?v=Rst4SvxMt3A remix]] from ''Nexus''.
* All four [[http://www.youtube.com/watch?v=1EiNKjHHLNc versions]] of "[[http://www.youtube.com/watch?v=c_P14FlamqU Silent]] Line", from the game of the same name.
* The intro and [[http://www.youtube.com/watch?v=J-XQELx4-b8 Overture]] from ''4'', both of which are chillingly good.
* From ''Armored Core 4'', [[http://www.youtube.com/watch?v=FYHv1h7-12E "Thinker"]] is absolutely amazing. To add to this remarkable song, an OverClockedRemix called [[http://www.youtube.com/watch?v=7pDe2bRJLqQ "Goodbye, Thinker"]] will take this action-packed war song and make it hauntingly beautiful. Both amazing tracks. The sound team remixed this track in the form of [[http://www.youtube.com/watch?v=aBXhik9kt7U "Thinker -reprise-"]].
* [[http://www.youtube.com/watch?v=K2Nud4kLLQg "Panther"]] from ''4'', which is perhaps one of the best songs for an opening stage, and comes back again in "Marche Au Supplice", which pits you against four of the best pilots in the game, [[UpToEleven and even without any allies on Hard]], and the song only escalates the battle into a SugarWiki/MomentOfAwesome as you hear the enemies' [[OhCrap disbelief]] if you begin to take them out.
** Possibly the best moment of this mission is actually in the normal mode; if your partner gets taken out your client for the mission comes over the radio with a retreat order, and immediately after that your operator, who is normally cool and detached, comes back with "NO! Continue the mission... I know you can do this."
* [[http://www.youtube.com/watch?v=diTUPGCBobA "Fall",]] the final boss theme of ''4''. An intense, fast-paced fight song with an awesome DesertPunk-ish combination of guitar, drums and [[OminousLatinChanting vocals]]. Then you realise that the lyrics are in English. [[TearJerker Then you realise what they're saying...]]
-->[[spoiler:I've already fallen]]\\
[[spoiler:I don't want to fight you]]\\
[[spoiler:It's so hard]]\\
[[spoiler:Wanting you...]]
* [[http://www.youtube.com/watch?v=moGbUeXMl5E "Fall -Into Grace-",]] an action packed remix of "Fall" from the ''Sunrise'' album.
* Most of the ''For Answer'' soundtrack, but specifically [[http://www.youtube.com/watch?v=omcG1oJ6i8o "Someone is Always Moving on the Surface"]], [[http://www.youtube.com/watch?v=ofLUejugHUI "Today"]], [[http://www.youtube.com/watch?v=t_7BR0lbIqE "Curtain Fall"]], and the [[http://www.youtube.com/watch?v=7-w-F0HVhTc Outro]].
* Also from ''For Answer'', the [[http://www.youtube.com/watch?v=R2tyuG3Mjm0 "Spirit of Motherwill".]] [[http://www.youtube.com/watch?v=pt_d9YJgyqg It also has a remix]], seeing as how [[spoiler:its wreckage appears in ''Verdict Day'']] and [[spoiler: [[BonusBoss you can fight it again.]]]]
* [[http://www.youtube.com/watch?v=WEsY1Wljl0w "Remember"]] from ''For Answer'', its remix [[http://www.youtube.com/watch?v=zWOxJ5NpIy8 "Remember ~ on your memory",]] and ''another'' remix in ''Verdict Day'' as [[http://www.youtube.com/watch?v=Q_FCYsL9XBE "Mechanized Memories"]] for [[spoiler:the final boss, N-WGIX/v/ White Glint]].
* From ''Armored Core 2'', [[http://www.youtube.com/watch?v=czvJtf28-F0 "King Lear".]] Plays during Leos Klein's MotiveRant, and sets the stage beautifully.
* [[http://www.youtube.com/watch?v=E0HRB0yGFCc Artificial Sky IV]] in the end, as well as [[http://www.youtube.com/watch?v=uP-6ymEgH74 "On Satteloid"]] in ''Armored Core 3''.
* In the ''Armored Core'' games of old, there was the single player menu music [[http://www.youtube.com/watch?v=x-ykG6lle8w "Shape Memory Alloys"]], as well as the ''[[http://www.youtube.com/watch?v=umAbxRTRyvI AC2]]'' and ''[[http://www.youtube.com/watch?v=iq52vjTFMtM Nexus]]'' remixes.
* [[http://www.youtube.com/watch?v=XJMZQ-pTjpg Artificial Line]] sets an epic tone for your battle with IBIS in ''Silent Line''.
* Nineball's remix theme from AnotherCenturysEpisode ''R'', [[http://www.youtube.com/watch?v=0FPwjdaOhaw "Nine -novem-"]].
* [[http://www.youtube.com/watch?v=l9fnyVD7eL4 "Lament Over the Howling Age",]] which was the Garage theme from the closed beta.
* From ''Armored Core V'', we have [[http://www.youtube.com/watch?v=XnvqcSKho5w "Stain",]] the theme of the final boss, [[spoiler:Chief]].
** Got a [[http://www.youtube.com/watch?v=5R56ZXQhPu0 remix]] in ''Verdict Day''.
* The opening theme to ''Formula Front'', [[http://youtu.be/9ryVoHtxxyo "Fake Facer"]].
* [[http://www.youtube.com/watch?v=MeC2JdqgfJw "Blue Braze"]] from ''3'' is real sweet.
* [[http://www.youtube.com/watch?v=t4kthqxnqkA "Ambiguity"]] from ''Armored Core 1'' is downright beautiful. It perfectly captures the tragic nature of every Armored Core world, and the sometimes terrible things that the player does to get ahead in those worlds.
* [[http://www.youtube.com/watch?v=xkP7RpSkKCM "Mecha Dinosaur"]] from ''V'' and its remix from ''Verdict Day'', [[http://www.youtube.com/watch?v=PqOF-4swI84 "Scavengers"]].
* [[http://www.youtube.com/watch?v=ozHdnvOxgZc "Vanishing"]] from one of ''Armored Core V''[='=]s trailers.
* [[http://www.youtube.com/watch?v=1gL0lrM03H0 "V for Two"]], the song on the [[http://www.armoredcore.net/acvd/ teaser page]] on the official Japanese website, is a pretty cool piece of music.
* [[http://www.youtube.com/watch?v=0Z23y2AC_9E "Forgive an Angel"]] is amazing.
* [[http://www.youtube.com/watch?v=dVAtqYBUbS0 "Dirty Worker",]] which plays during the first mission in ''VD'', is a perfect blend of ''Armored Core''[='=]s old and current music direction while setting that feel of the next evolution in ''Armored Core''.
* [[http://www.youtube.com/watch?v=4od42cBGffA "Connected",]] which plays when you first turn on ''Verdict Day'', is awe-inspiring and sets the tone for the entire game.
* [[http://www.youtube.com/watch?v=2s0JDs6x_g0 "Death Count",]] which is the menu music for [[BrutalBonusLevel Hard]][[SelfImposedChallenge core]] mode. It gets the point across.
* The theme for when [[spoiler:you fight [[FaceHeelTurn Maggie]]]] in ''Verdict Day'', aptly named [[spoiler: [[http://www.youtube.com/watch?v=SSR1kOBzPUM "Blue Magnoria".]]]]
* The song [[http://www.youtube.com/watch?v=q3ipyzisX1Y "Day After Day"]], which plays in the "No future for mercs" trailer. Along with the [[http://www.youtube.com/watch?v=p-EuE1lSF5w live version,]] and its [[http://www.youtube.com/watch?v=ql8KgsC7vjE cover]] which is almost as good as the real thing.
* ''Verdict Day'' got Soundtrack DLC, which means more awesome music. This is mostly remixes of old songs, most notably another remix of [[http://www.youtube.com/watch?v=E5vup40fUl4 "9"]], a [[http://www.youtube.com/watch?v=ecxsCas8UQA "Cosmos"]] remix that replaces [[spoiler:the final boss theme (which is also from ''For Answer''),]] and a remix of [[http://www.youtube.com/watch?v=oYWo84D2-L0 "Dirty Worker"]] which has [[SugarWiki/FunnyMoments Fatman singing the song.]]
* Each of the three factions in ''Verdict Day'' has their own theme, all of which make scrolling through the main menu an enjoyable experience; [[http://www.youtube.com/watch?v=-wjNvovMo9k "Venide"]], [[http://www.youtube.com/watch?v=e4zZqkWSQhQ "Sirius Executives"]] and [[http://www.youtube.com/watch?v=2KpKUIC2asI "Evergreen Family"]].
