Try pandora. http://www.pandora.com/ It has a very interesting interactive search feature that allows you to find more music based on your reactions to the songs played from previous searches. For example, type in “The Meters” and it will generate a whole list of funk and New Orleans music. If you like a song, you can tell the computer to find more similar music, so that leads you on to Big Chief Jolly and the Wild Tchuopitoulas, or to Irma Thomas, and so on, depending on what you liked or didn’t. It will also ask if that song is what you were looking for, or not, and in his way each search builds upon the previous. I haven’t done much with pandora yet, but apparently you can save your searches and make playlists with the stuff you turn up.
