Beautiful!
You should feel special! I've been coming to NG for years but never got an account. YOU are the sole reason I signed up; to review this song!
An excellent piece of nostalgia and summary of my childhood!
You've done one of those rare compilations of boss music, and you've done it well (even rarer!)
I absolutely LOVE your renditions of the individual themes, they truly capture the spirit, feeling, and context of the originals.
Do you have any intentions of releasing the songs as their own individual tracks?
SIDE NOTE: I just have to give special props for the Sonic 1 Bosses! So few can do those two songs well, but you've certainly succeeded where MANY others have failed!
