If I were looking for music sharing communities I think I would be asking about that with a more specific goal.

I think saying there is not interest in having a bandcamp community is a silly notion, there’s enough practical reasons over the even shittier streaming options and compared to going to each artist individually, not to mention lemmy as a whole is a link/conent/information/etc aggregator in the form of communities sharing info about everything so meta information alone warrants the existence of it as a community, you mentioning the things about epic gamesand songtradr is a good example of something to go there.

Over time I’ve been watching bandcamp grow and still be as useful as it ever was, in fact it has enough artists on it now that it seems like a worthwhile endeavor for me to use it, thr main thing that got me there recently was a recent push to use bandcamp because of the spotify ceo thing and a few notable artists of mien moving their main front to there.
