Last.fm is a streaming audio application that keeps tracks of what songs you like or dislike and recommends new music based on your taste. The interface is simple and displays the album art as well as the controls. Loading the song initially can be slow, but it only rarely has to pause to rebuffer. The Last.fm app can play your music in the background so you can use other applications on your Android device. I have always dreamed of having the music I like streaming from the Internet to my car...
