I develop kew (a terminal music player), so I’m biased, but I started kew because I rejected Spotify many years ago.
I think that kew (or other private/offline music players) together with flacs from Qobuz are actually a great alternative to Spotify. Throw in some Bandcamp albums in there for great justice. Once you have a decent collection, you will feel liberated.
I especially think that Qobuz needs more exposure.
Just buy music, for instance flacs on: https://www.qobuz.com/shop
Then use a local player. Might I recommend: https://github.com/ravachol/kew
