My primary (and now only) use case of Bandcamp is as a marketplace between me and the artist/label. I use it as a super convenient record store. And like a good record store, bandcamp also has the equivalent of music magazine which you can read in the store, and helpful staff willing to point you to new releases. and just like in a record store, the staff won‘t play what they recommended for you, you have to take the sample CD to the listening station, put on the headphones, and hit play your self. I see their streaming feature as basically a super convenient listening station at the record store. I usually stream an album before I decide whether or not to buy it.
After purchasing I never listen to it again in app, but rather download the files and upload to my MP3 player, or wait for the physical media to arrive and listen to it in my living room’s stereo system.
Bandcamp also has the equivalent of a radio station’s music oriented talk show with their podcasts, this is more then your average record store. E.g. I think Easy Street in Seattle nor Lucky Records in Reykjavík have a regular podcast, although I can see it could be amazing if they did.
