YouTube
The service will be called YouTube Music Key, and it'll initially launch in beta which means it won't be the final version. It'll cost $7.99 per month and will give you access to ad-free music, the ability to play songs in the background even when the YouTube app is running in the background, and offline viewing. Google is also throwing in a subscription to Google Play Music.
The idea is to make it easier to use YouTube as a music service similar to Spotify - at least that's the way Google describes it in its blog post. Now, you'll be able to browse through an artist's full discography.
Google is starting by adding a new section just for music within the YouTube app that shows your favorite music videos and recommendations.
