It is most popular site for music database. It creates music profile of users by collecting information by it’s audio player software which is compatible with most of the music players. On Linux amarok independently has functionality of submitting information about songs you played.
You just need to sign up and install the software. Profile building is completely autonomous as you play songs. Build profile is really cool. It also suggest songs you like. It shows your favorite artists and track. It can also prepare many kind of charts based on your taste. You can compare your music taste with your friends. The installed software also shows information about current playing track. It keeps track of all songs you have played and shows average tracks played by you weekly, monthly, yearly and overall.I am a great fan of it.
