I would suggest using InnerTune and ViMusic, which are free and open-source client for YouTube Music, if you don’t want to let Google advertise on you.
However, you may need to build your music library all over again, as they doesn’t support import from your YouTube Music library.
If you already switched to Spotify, then you consider Spotube and BladePlayer which seems are free open-source Spotify client, although I haven’t tried these two.
