I've gone through quite a few of the music streaming services now. I was on Rdio for a long time until it (sadly) shut down, switched to Spotify for a while, then to Google Play Music, and as of yesterday I have access to YouTube music (which it sounds like is intended to replace GPM before too long).
From a quick glance at YouTube Music I'm a bit worried—the "library" functionality seems pretty limited, and the search isn't really working as I'd expect. It also doesn't seem to have any connection with my GPM collection or playlists.
I think it's been out in the US for about a month now, has anyone been using it? Any thoughts on it so far or suggestions about using it?
