Google officially released dedicated YouTube music app for Android users. This app is dedicated entirely to music. It’s free to use, just like regular YouTube. It pulls up music videos and turns them into an endless stream of songs.
Think of it as radio with a video component. You can’t really create playlists, aside from putting together a giant list of all the songs you’ve ever liked. Though you do have the option to tweak your stream to introduce more variety.
