I've recently adopted this model (though I've been buying on the iTunes Store as it's DRM free and I have a hard time finding the larger or really tiny artists on band camp). Plexamp has been awesome and while I miss the discovery of Spotify, I am glad I left. I was a customer from 2012 to 2023 (11 years) which is kinda nuts when you think about it.

Another good place to get DRM free music is 7Digital! That's my go-to place when Bandcamp doesn't have it. Their prices are often a lot better than the sites that cater to audiophiles, though you can still buy high-res FLAC there if that's your thing.
