Alright, how about some Game Boy Advance music this time? GBA sure had alot of titles, and among them many good tracks. I'll leave here some of my favourites.
Golden Sun - Venus Lighthouse (Perfect song for any last dungeon)
Castlevania Aria of Sorrow - Ruined Castle Corridor
Mega Man Zero 4 - Esperanto
Zone of the Enders Fist of Mars - Main Menu Theme
Sonic Adventure - Egg Rocket Zone
Gyakuten Saiban - Cornered
