In Finland we have had a personalizable internet-radio operating for a few years already. Zoice is a personal radio that customizes the music according to personal preferences. It uses learning algorithms to adapt the music according to taste of user. More the user gives feedback of like or dislike of some song, better the system can match the user profile to other users and to different kinds of music. However, each user gets his/her individual radio feed, as user can choose never again to hear some song.

The service language is in Finnish, but it plays international music.
