Nope, no metal. The only song I'm doing that's close to metal would be the alternate version of Dr.Wily Castle 1(which will play on the 2nd Castle level). I have some guitar in Iceman. Might put some guitar in the Title Screen, not sure, haven't worked on that one at all yet.
Cutman has alot of trumpets & castanets, various songs have violins. All the songs are mixed with other related songs. For instance, I mixed several versions of Cutman's theme, as well as some other latin based or blade based MM tunes from thruout the entire series. Bombman was the hardest to find tunes that were similar either in theme, or sound. He didn't appear in the GB game, or MM Soccer. I ended up taking some stuff from Burstman as well as any song from the series that is set in a city, since that's the main thing I think of with his level.
I'm almost tempted to set up a youtube account or something & upload all the songs that are finished. Was wanting to hold back till it was 100% done originally.
