Uma comparação entre dois operadores de música na net

a Pandora e a Last.FM

"Last.fm is great.  It requires a number of things from you.  First, that you listen to a lot of music on your computer.  If you don't there is no way for last.fm to capture your music listening data.  Second, that you download the plugin so that they can in fact capture your music listenting data.  And third, that you are interested in an online social experience for discovering music."
