>If you are a subscriber to Google Play Music, good news, you get a YouTube Music Premium membership as part of your subscription each month. Calling it now, within 5 years there are at least 5 different Google services for streaming music (up from 3 now, Play Music/Youtube/Youtube Music) at least 2 of which are also somehow messaging apps. It's even plausible, one for VR music videos, one for streaming in your self…
YouTube already includes comments and a chat on live streams, so close to a messaging app ;-) Seriously though, YouTube is not a music service, or at least it looks like they don't want it to be, since the interface isn't really great for that case. It also kills phone battery if you use it that way, so YouTube music is an experience upgrade.
Based on the press release, it doesn't seem so. It's basically just added a "music only" option, but otherwise it seems to just be a curated section of Youtube that only involves musical content. The same experience you get with vanilla Youtube seems to be applicable.
And looking at the pricing, you still get all the battery pitfalls baked into Youtube unless you buy premium.
Honestly, it feels more like an attempt to curate Youtube rather than developing a music app. Right now the top video content competes with the published Music content and likely just creates a really weird imbalance in the algorithm toppers.
Personally, I think they could have just handled this with some better organization within Youtube, but here we are with a new app.
