The Last.fm App. If you have a Last.fm account for the love of all that is good download this App. It can be found in the installer it's called MobileScrobbler I think. It's got all the functionality of the actual computer app. It's incredible! You can type in an artist into the search bar and click play similar artists and it will use WiFi to play full songs and all that just like the computer app. It scrobbles your songs and if you are not in a WiFi enabled area is queues them and then scrobbles them once you get into a WiFi area. It is truly an incredible app. Even if you don't have an account you should check it out, I think it would still work.
