Regardless of the fact that there were already two attempts made to the Sonic & Knuckles music, it would be great to have one that stays true to the original melody but uses more updated synthesized instruments in place of the original MIDI sounds. Not that the original music is out-dated in any way but it'd be nice to listen to this already catchy music but with a bit more pop & pizazz.
And just out of curiosity, it'd be interesting to hear what a jazz arrangement of Metroid Prime would sound like.
true religion
Oh, and a full-blown arrangement to Rocket Knight Adventure would be awesome! Perhaps even bundled with the original soundtrack which was never officially released?
