Since I got the okay from a mod, can we have another go at this? Pretty please? Also I guess post a link to a YT vid for the song because they should all be there.
For me, Closure, from Ace Combat 5, hands down. You can whine about the mission all ya want, but that soundtrack always puts a smile on my face. I found it good for studying, too.
Emancipation, Operation Bunkershot, Comona, Ancient Walls, Mayhem are all honorable mentions for me, too.
