youtube 2YouTube has a ton of music videos. But today, an alert reader, Ron Ilan, spotted something new: the YouTube Music Discovery Project.

It was launched quietly today via TestTube, the test labs at Google’s YouTube division. You type in the name of an artist or group in a search box. Then you hit the “Disco” button to find music. A playlist will appear as the search result.

I typed in “Plain White T’s” and the band’s hit song/video Hey There Delilah started playing. You can also see a description of the band. You can find artists who are related to the one that you searched for. You can create and save your own playlists.

Playlists show up in your own YouTube playlists page. Then you can share them with your friends.
