Grooveshark, the much beloved alternative to Pandora (US) and Spotify (UK) is out..OFFICIALLY! Which means you don't have to rely on a jailbreak and can expect the app to run a lot more smoother. Furthermore the app comes with a 30 day free trial, after which you have to pay $3 a month, just $3! The app is pretty neat, you can save playlists and even make them offline for listening whilst you have no connection. You also have a radio feature similar to Last.fm Enjoy it peeps, I sure will!
