The world’s largest (and my favorite) music social network, Last.FM, has officially partnered with Logitech, whose Squeezebox and Squeezebox Duet network music systems will now scrobble the tracks you’ve been listening. The Last.FM's scrobbler is a software which detects the tracks you’re listening to (it uses plugins for various types of music listening software, such as Winamp, foobar, Windows Media Player etc), and adds them to your online profile on Last.FM.
