YouTube Music Key was recently launched as a new way for people to enjoy ad-free music on the go as part of a paid monthly subscription service. For $7.99 monthly, what you'll get with a subscription to YouTube Music Key is access to Google Play Music, offline videos and the ability to listen to music in the background while other apps are up and running.
With a Music Key membership, you'll see a new tab on the YouTube app and site called 'Music.' Clicking this will show you trending music videos sorted by genre. As well, YouTube has curated several mixes for chilling out or pumping you up. The more you listen, the better the results of the 'My Mix' playlist will be, which tailors music based on your preferences.
