ExtremeTech has published a roundup of 8 music recommendation sites/services, including:
* Yahoo LAUNCHcast Radio
They ran each of them through a series of tests using different artists and genres, and then compare and contrast the various features of each one, and the quality and quantity of the recommendation engines. The verdict? Last.fm and Pandora ran at the head of the pack, with Last.fm receiving top honors. My personal experience with Last.fm echoes this enthusiasm…if you are a real music geek, Last.fm should be at the top of your bookmark list.
