Google has been rumored to launch a YouTube-branded subscription music service for months now, and were getting a big look at what it might entail when it finally launches. Android Police is reporting that the service will be called YouTube Music Key, which will offer ad-free playback, the ability to save songs and videos for offline listening, and an audio-only interface for when youre multitasking or want to have music on in the background, all for $9.99 per month. It sounds like basically every other streaming music service out there, including Googles already-established Google Play All Access service — but at the same time as YouTube Music Key launches, Google is expected to rebrand its current offering to Google Play Music Key. It also sounds like a single $9.99 monthly subscription will include access to both the Google Play and YouTube music services.
