Last.fm is an online community that lets you record, share and listen to music and define your personality through other people's art for the whole world to see. Basically, it's myspace all over again. Without the garish layouts, thankfully.
Last.fm is an online community that lets you record, share and listen to music. Users submit their playlists via some plugin and each MP3 is tagged and gets posted (»scrobbled«) to their profile while played, and to marketing researchers who can make good money from all this free data.
People may organize groups and open discussions about whose favourite band is the most obscure, but most important: they feed the system with info about artists' bio- & discography and automatically deliver statistics on what track is played how often and by whom. Why anyone should care what that weird kid from high school is listening to at age 39 remains unanswered.
