Looking for some good music, but don’t want to get sued by the RIAA?
www.live365.com is cool if you want to find a digital radio station that closely resembled a regular radio station, complete with DJs and call in lines (in some cases, other stations just play music, no talk!) Live365 does have ads occasionally, but it typically is just one 30 second ad every four or five songs.
www.pandora.com creates customized radio stations that you customize by telling the site a song or artist that you like, and it starts building a station up based upon that initial artist or song. You than thumbs up or thumbs down songs that play, based on if you want more or less songs of that type. It sounds a bit strange, but it works really well!
