There''s this new site iNOIZ.com that has all this music from game developers. Some of it has been used before but a lot of it hasn''t. There''s a search that allows you to search by key word or genre. What''s really cool is that they have 12 types of content that you can use to make a game. (sound fx, textures, wire frames, animations, etc..) All of the stuff is previewable and they don''t charge you anything to join. Pretty cool stuff.
