Google’s long-awaited YouTube music subscription service is finally taking shape, according to reports from Android Police. The blog reported Monday that Google is preparing to launch a service called YouTube Music Key and rebrand its Google Play Music All Access as Google Play Music Key to match. YouTube Music Key will give users music without ads, audio-only playback and offline playback. What may set it apart from the pack of streaming services is YouTube’s vast library of concert footage, covers and remixes, giving devoted fans much more than their favorite artists’ official discographies, according to Android Police.
