To scrobble is the act of sending information of a currently playing track, or song, to Last.fm. Last.fm is a free service that recommends and suggests music by discovering new music based on the music you play. In short, it’s a social network that focuses on music and artists only.

Like other social networks, you find and add friends in order to share your musical tastes with other people and to discover the musical tastes of friends…

Scrobbl is a small program for the iPhone that sits in the background (as a MobileSubstrate daemon) listening for songs or podcasts to be played through the iPod.app. As each track is played, Scrobbl sends a little note to Last.fm with the details of the track being played. The track then appears in your Recently Listened Tracks feed for you and others to view…

Scrobbl is available for free in Cydia. The current version, 0.9.5, supports iOS 3.0 to 4.1. Additionally, there’s a SBSettings switch just for Scrobbl, SBSettings Scrobble Toggle, that let’s you quickly, and easily, enable or disable Scroll from sending track information to Last.fm from SBSettings.

Please note that the this current version of Scrobbl does not support status bar icons, and as such, you will not see Scrobbl’s icon indicating its state.
