Personally I wish all these music streaming services could agree on metadata sharing such that I could enable apps like last.fm to review listening history across every service, and offer my listening history and playlists to every service to receive better recommendations. It feels odd that I can listen to the same song from 4-5 different services that I subscribe to legally, yet none of the services has a complete picture of what I like to listen to unless I pick one and use it as often as I can. I had thought that playlist sync would be a way to improve my recommendations, but it seems most services look at listening history rather than playlists. It's also irritating that every company has its own way of doing playback sync between devices, whether it's AirPlay, ChromeCast, Spotify Connect, Alexa, YouTube app, etc. There is no way things should be this fractured and hard to use for music playback and recommendation in the next decade, we need more standards. :)
Youtube Music's handling of my uploaded music is really poor compared to GPM (sectioned off from everything else), so that alone was enough to make me dump my subscription when GPM was shut down.
Now I run my own Plex server on a Raspberry Pi with an external drive and get a better experience than I had before, minus discovery.
I actually prefer the way YTM segments my uploads from the general catalog, as it gives me some possibly unfounded confidence in the idea that I'm going to be listening to the edition I expect, and not something like a 20th anniversary re-release with 15 extra tracks. GPM has this really bad problem where their treatment of my uploads was seriously broken and I would see, just as one example, multiple copies of every track on one album. I don't see this since the YTM conversion.
