I'm building a library of music I can keep forever, even if I stop using the service. Some months I don't pay anything because I'm happily listening to what I already have. I'm not stuck paying a subscription
musicians get a good cut
their blog posts about genres and cities and stuff are good, and are (or feel like they are) written by an actual person.
Sometimes musicians do "listening parties" where you just hang out in a livestream with the band
when you buy stuff, you can write a message to the band and sometimes they write back
Now, if nothing you listen to is on bandcamp it won't be as appealing. But there's a wide variety of genres.
