MobileScrobbler is a last.fm client made by Sam Steele. Let me start of by saying that this application is AMAZING!!!! The whole point of last.fm is to discover and share music. Once you install the application, you have to log into your last.fm account by going into your Settings and then selecting MobileScrobbler (the settings for the app are added as an option in the stock Settings.app). In the MobileScrobbler settings you are able to disable scrobble, which is the act of posting information about the song you played last on your iPhone or iPod Touch to your Last.fm profile. You can also change the theme, enable or disable gestures, popup controls, and discovery mode. Once you open the application, it shows information like Play Recommendations and Play my Playlist.
In Charts, it has information like Top Albums and Top Tracks. For some reason that feature is not working for me. The MAIN part of last.fm is obviously discovering music. You can search for music by artist, tags, or user. Once you search, it will play a song that it finds. You can see the lyrics, artist bio, events, and song info of the song. There is a ton of information. It also recommends other bands that you may like. If you hit the Home Button and go back to the SpringBoard, the music will continue to play in the background. This is an AMAZING application for discovering and playing music. I highly recommend it. You can get this application from the Ste Package source.
