http://www.vgmix.com I heard about this site a while ago and visit it quite frequently. It's basically a place where people send remixes and new renditions of classic videogame songs in any style they choose. Some of the stuff is good, some not-so-good, but it's always fun to look through what they have and rediscover a classic tune that you've always loved in a new, updated style. You fans of the original NES Mega Man games should be happy, as well as fans of Chrono Trigger. There are ton of adaptations from these games listed on that site.
