A Few Notes of Elton John in Mega Man 2's Soundtrack
Mega Man 2 was/is one of my favorite games of all time. The gameplay, graphics, music...oh, the music! So it turns out that a lot of the music might've been possibly inspired from elsewhere allegedly. Doesn't matter to me one bit however; the game's still near absolute perfect.
Worth checking out the comments on the Kotaku post for further examples...
