Mega Man 2 is indeed my favorite of the series but it's refreshing to hear some of the tracks from 1. I only wish they would team up to cover the rest.
Favorite track: Hell Has Frozen Over/Fire & Ice.
This is simply mind-blowing. Great harmonies, great lyrics, great music all around. Even if you've never heard the original/played Megaman. If you have, it's just that much better.
Favorite track: Evolution of Circuitry/Elecman.
