Mega Man ZX's soundtrack is absolutely amazing! It's songs are so God damn good and it's easily in my top 3 Mega Man Soundtracks. If you thought the DS Soundtrack was top-tier music, then the Tunes soundtrack is even better. My favorites are Awake, Fragments, Green Grass Gradation, Industrialism, Danger Attraction, Misty Rain, Fate, Crisis Zone, Trinity, Rockin' On, High-press Energy, Onslaught, Trap Factory, Doomsday Device, Black Burn (Original and Electpital Dance Version), Dream Weaver, and basically, the whole damn soundtrack.
Soundtrack: 9.7/10.
