Introducing Music Key, a new subscription service from YouTube that allows users to listen to music on the platform without any ads. You’ll be able to listen to tracks offline or listen to them in the background while you’re using other apps, all for a nominal fee of $7.99 per month which will go to its regular price of $9.99 sometime next year once the promotional period expires. Music Key will be in beta for now and will also include a subscription to Google Play Music. That’s access to 30+ million songs, tailored playlists, and in the coming days, the ability to watch many YouTube official music videos right from the app. If you haven’t gotten an invite, you can express your interest in Music Key here.
