Flight stuff.Ace Combat Zero Theme, simply to get that out of the way. Pretty sure you can find a higher-quality recording in a few seconds.
Area 88's
We Know What You Did,
Awakening,
Spread Your Wings, which sadly has a lot of lyrics but would have gone beautifully with parts of WoD1 anyways I think, and Temptation (I can get you quality of this stuff if you need it, it's not easily to get ahold of)
Magical Girl StuffIgnoring Nanoha OP/EDs because they have lyrics, and frankly the EDs annoyed me most of the time. Ignoring Brave Phoenix, Take A Shot, Pray, because they have lyrics.
Raising Heart, Set Up! can probably be sliced up for allied arrival sounds and or possibly whole for briefing music.
Raikou Shuurai chopped up for enemy arrival music or used whole for general Bad Things Are Happening
Subaru's Theme could be used directly for battle music, and probably other things.
Teana's Theme, main menu, tech room, briefing?
The Athra's theme, briefing, main menu, tech room?
More when I can be bothered to go through my A's/original soundtracks in detail
