As a musician once on there, I joined, spent a lot of time carefully designing my page and uploading my catalogue, and then I paid $20 a month for their premium service for absolutely no traction on the site beyond external promotion I did. The UI on BandCamp has been vastly outdated for ages now, it was very hard to navigate and find new music by genre. i only go there to buy music if I have a direct link. It's a pr…
Once you get to an artist's page, the UI is simple and clean and Just Works. I can see their releases, buy and download them easily. That's what I want when shopping.
Imho, Bandcamp shouldn't even offer that kind of $20 "promotion subscription" thing you mention. Just sell music, take the cut, and be done with it.
Honestly my only real UI complaint about Bandcamp is that artists often move between labels and collabs and the label runs the bandcamp page so their music is mixed in with all their labelmates. That's where I find it gets very confusing. Like most of Lauren Bousfield's albums are at
https://laurenbousfieldanyev3r.bandcamp.com/
except her latest album which is here:
https://orangemilkrecords.bandcamp.com/album/salesforce
and is not linked from her personal page at all. Another album (Palimpsest) is linked from her personal page, but if you click on the artist of that one it takes you to a different label (https://deathbombarc.bandcamp.com/).
So obviously something is horribly wrong with navigation in how it handles labels and the like.
