I've only checked the place out a few times... I'm not really a fan of Super Nintendo music, but seeing how many people here have interests in game emulated music, I'd figure it's worth mentioning here. Hope I don't get banned for advertising a site, afterall it does relate to a common theme and it's not solicitation or anything.
