Mighty...
...though a bit too loud for my taste. This song starts of with a blast and moves on in that direction till it's end. I am not a fan of Megaman, but I can easily imagine this theme in a game like that - it meets it's purpose, and that is too bump up the adrenaline I believe. However, this is not something I'd like to listen to more than once, could be just me, but I find little variety and it just seems to go on and on, making it more suitable as a game music than a song on it's own.
