All I can say is the best thing to do I read up on the type of music you like. Find an artist or two and see who they have worked with. If the band broke up see where the members went and get the records with the new band they are with. I find this works alot because musicans seem to keep the same style for awhile. As when you can get music you like so that way once you sample one sound you can still listen to the album.
