I wish more artists would sell their music on Bandcamp. I use jellyfin for music but acquiring music is difficult.

If you can't find a place to pay for it, then just do what Spotify did when they launched. I recommend Nuclear[0] for that

Why is acquiring music difficult? If it's DRM you're worried about, the iTunes Store is all (or at least primarily) DRM-free.

Between Bandcamp, 7digital, and Amazon (which I check in that order), I have always been able to find anything I was looking for.
