Pandora is one of my favorite music sites. It’s a quick way to get an infinite play list built around a song that you give it to start with. I’ve become a fan of several artists that I heard on Pandora for the first time. I hear that their catalog of music isn’t nearly as large as some other well known music sites, but I could never tell any lack of grat music. So Pandora is pretty excellent… except they were in danger of going under due royalty rates that they were being charged.
