Last.fm is a free online music streaming service. It keeps track of what music you listen to, and then produces web radio station personalized to you.

You can use Last.fm to listen to music, find out about artists you may like, other people with similar music taste, gigs in your local area, charts and quilts for your personal site, as well as much more.

Web Radio Station Modes Last.fm offers:

• Personal Radio gives you an insight into a user's entire profile. This web radio station's content is built up based upon every song that the user gets scrobbled to their profile, via a plugin or the online radio service. Anyone can listen to the personal web radio of another user.
• Neighbours Radio is a web radio mode in which it will tune into a web radio station made up of all people listed as a neighbour to that person. With Neighbours Radio, it's easy for a user to discover some music that may be similar to the music they like, and as such help broaden their music tastes.
• Loved Tracks Radio is a web radio mode which is a Subscriber benefit, much like the Personal Radio. Audio tracks that will feature on this online radio station are tracks that the user manually marks as "loved".
• Group Radio is a web radio mode that is accessible via a group's page. This radio mode simply plays you back a radio station full of songs of what's within the group member's profiles.
• Similar Artist Radio is a web radio mode accessible via an artist's page. The songs on this online radio station are based upon system generated "Similar Artists".
• Artist Fan Radio is another web radio mode found upon artist pages and the such. Once tuned into this online radio mode, you'll get audio tracks played to you from the profiles of users deemed to be fans of the said artist.

Please note that Last.fm is not an on-demand music service. It is licensed as a radio station. If you like to listen to a specific song you should wait until it pops up on your online radio station (unless the label have specifically enabled the track for full-length preview). But you can listen to a 30-second preview of any audio track.

It's free to sign up and use Last.fm!
