if you don’t mind downloading the music then Nictoine+, it’s a GUI for soulseek. essentially Napster/Limewire. Anything you can get on spotify you can pretty much get there.

Keep in mind, like Napster, it takes time to find things you want. If you have your own server or hell even a cloud server with unlimited bandwidth and a good chunk of space you can put your music on there that way you can just stream it to whatever device you use to listen to music. Essentially a media server.
