YouTube launched its own music playlist maker, dubbed “YouTube Music Discovery Project,” which’s now out of TestTube. The page is a search box on top of which says, “Find>Mix>Watch,” and once you enter a name, you hit the “Disco” button to find music. You can enter any music group or artist, and a playlist pops up, along with a thumbnail video and a description of the band. You can find related artists, create a mixtape, and save playlists. As you’re listening to music and watching videos, it’s easy to add and delete songs.
