Liveplasma

www.liveplasma.com/

While we're on the "if you like that then you might like this" genre, Liveplasma is an awesome website for finding new music. You give the site an artist or group name and it creates a web of similar artists and groups. This website is a bit more interactive than Pandora Radio but it does not play the music for you like Pandora does. But what is nice about Liveplasma is that you can also do the same kind of search for movies, directors, or actors that you like. Also I just like the way it creates a web of artists that are then grouped and located according to how they relate to the central artist.
