Earlier quoted context omitted.
One can stream on bandcamp, through an app or the browser
can one stream a mix of music sourced elsewhere and bandcamp music? If people have to keep switching apps, I think that's going to limit the appeal to people who are a bit more serious/intentional about every "listen". There's a lot of those, but it's still a minority.
It’s actually one of the reasons I use Apple Music over Spotify, the process to do this in Spotify is much more convoluted.
