You should be able to control every music streaming app from the desktop notification if you use KDE Connect. I use Tidal nowadays, which isn’t open source but it’s a very good streaming service. It normally costs 11€/month but the family plan is 17€/month for up to 6 people. Even if you only have 2 people in the plan it’s a lot cheaper than the individual plan or Spotify.

Tidal now seems to be cheaper than Spotify. The algorithm gives me pretty similar stuff to what I got from Spotify. I find the desktop app okay.

Big pro they pay the artists better than Spotify does. Another big pro for me is the integration with plex.

Disclaimer: I’ve only had Spotify and Tidal, before I’d just download music, like buying it on Beatport or Bandcamp and host it on my own plex server.

I’d like to find something that lets me control the music from my desktop, either through KDE connect or a standalone app. FOSS / F-droid preferred

I recommend a self-hosted music server like Navidrome. [email protected]

This may fit the bill some? Harmonoid It allows you to use your local media.

If you don’t mind internet radio, there’s always Radio Garden which allows you to stream any station from almost anywhere in the world.

I used YouTube music revanced but I’m not sure if it has all the features you would like

I just lookup stuff on YouTube via NewPipe; sometimes I might rip a Bandcamp album and listen to it with a media player (Metro)
