YouTube Premium and YouTube Music Premium have expanded to 7 new countries - Chile, Colombia, Japan, Peru, Portugal, Switzerland and Ukraine - bringing the services' availability to 29 and 21 markets, respectively.
The two services share the music part but differ overall. YouTube Music Premium costs $9.99/month and brings the entire former Google Play Music catalog and YouTube's exclusive mixes, covers and live performances.
YouTube Premium includes Music Premium but adds the full YouTube experience, adds background and offline playback along with exclusive YouTube original series. It costs $11.99/month.
Oh great, like they aren't making enough money already - they are now charging people for their app. While "old" youtube is getting more and more adds - pretty much turning into junk.
For YT: New Pipe - nothing compares with it. Free and open source.
