This was the final straw for me.
As a developer who needed access to both, for years I ran Apple and Android side by side. Sometimes I'd switch the SIM over literally weekly depending upon mood (the danger of account loss in both cases is so high that nothing I do beyond app purchases is ever tied to or held against my Apple or Google account as that means placing all my digital stuff at the whim of huge corporations with no practical customer service).
I have MP3s. Curated and organised. The world of tech is heading for rental of everything possible (and the time will come when it is unaffordable with so many subscriptions) so I see no reason to abandon what I already own in order to pay for it again every month forever.
Then Google removed Play Music (and hence the online library). I know there are alternatives, but there was no need to destroy localised music on the phone. It was a totally cynical means of creating new subscriptions for YouTube Music by leveraging the Android platform. Very much not good and probably mono/duopolistic legally speaking.
So now I'm iPhone only. Not out of love for Apple (I used both side by side for years), and not out of naivety, but because daily the forced choice of the lesser evil drives Google ever further from consideration. By targeting my audio it hit me where it hurt, and there's a price to pay for that.
Despite death by a thousand cuts, in the end each of us has a red line somewhere; the pure, greedy, duopolistic, arrogant cynicism of the death of Google Play was one such for me.
It works really well. It has the playlisting/queueing metaphors that I prefer and it has a decent interface for finding things or even playing all of the albums from a specific artist.
I felt that pain. I would be interested in something self hosted that looked and felt similar to Play Music, but I have yet to find one.
Edit: Then I scrolled down a bit more and saw someone linked to Navidrome. It might suffice for me. https://www.navidrome.org/
It simply worked for my old folderwise-kept mp3s etc, and it also displays embedded lyrics in the mp3 files which was a killer feature.
It's not that I love this app dearly, it's just that it got the job done and didn't need replacement.
Try VLC. That's what I settled on also.
It's simple and just works.
