Last.fm, Free

Much like Pandora, Last.fm makes it simple to stream an impressive collection of music to your iPhone without ever paying a penny. Like those offerings, Last.fm lets you start a station based on an artist, then tweak from there, based on what plays. You can also view artists bios easily, tag them as favorites, find out tour dates, and Last.fm’s social approach to music lets your friends know what music you’re currently enjoying and vice versa.
