Not tor, but you should look into funkwhale for hosting it after you’ve sourced it. I’ve been pretty happy being able to stream my music from anywhere for free. And other people’s music, podcasts etc.

I use funk.gravitywell.xyz because it had a great amount of free storage, mostly stoner/doom/prog/metal music from.myselg and others.

Here’s there “find the pod that’s right for me” tool:

Caveats: the music needs to be in good condition and properly tagged. The funkwhale app on Android crashes more than anything else on my phone. Which isn’t much. 1x a week, normally after using voice input.
