Its a website you make an account and download the file for whatever music player you use and it keeps record of all the tracks you listen to and makes pretty lists weekly, top artists, most listened to songs. Heres Mine: http://www.last.fm/user/THF20 Also the search feature is the best among any say you wanna listen to a band dunno anything about em. Search em you'll get a comment list of fans, similar artists, bio, maybe even a full song or clip of the artist it varies amongst artists to artists. Its quite good... -unsure
they are just playlists of songs... you can't listen to all of them. try radioblogclub.com for songs that you could actually listen to.
