Youtube just launched a new service called Youtube Music Discovery. It allows you to automatically generate playlists based upon the name of an artist or band that you like.

The interface shows two columns: on the left, a playlist automatically generated depending on the artist you chose, with a video player on top of it. The right side of the screen allows you to search and add more tracks to the playlist.

The playlist can be saved for later use, but can not (yet) be shared with friends. Another question remains: how many tracks / videos in the automatically generated playlists are infringing copyrights?
