Big fan of Bandcamp here.
Supporting artists directly, physical music purchase etc aside, the cheat code/secret sauce imo is the "Collection" aspect.
A perfect v4v music app for me would be Bandcamp but w/ a Boost-to-add-to-collection feature. If I boost, get to "showcase" the music as part of my public collection. We're social creatures at the end of the day, and personally, I'm proud of my collection of music, it's an extension of me..
