Last.fm is a music service that lets you discover new music you like, based on the music you already listen to.
The Last.fm website is filled with tons of information on artists, albums and tracks, more music similar to them, charts and other statistics and more, all built by the Last.fm users who’re keeping track of what they’re listening to with Last.fm. (If you want to join them and get your own profile with your personal charts and stats, read the next question for more information.)
You can read about artists you like, check out their most popular tracks, browse their album and find out what other artists are similar to them; learn about upcoming events, explore interesting genres, listen to music and watch videos.
To get the most out of Last.fm, sign up for a user profile – you can build up your personal user profile, write journal articles about your favourite music, create your own event calendar and invite friends, talk to other users and get together with them in groups about interesting topics.
