I don't think there needs to be an alternative, but Bandcamp needs to put more effort into getting more artists on its platform and for those artists to expand their catalogs. I buy a lot of albums on Bandcamp but it's annoying when I see a new release somewhere and the artist isn't on Bandcamp, or when an artist only puts their latest album there.

Bandcamp could also put more effort into recommendations based on a user's purchases, or just when viewing an artist's page. Not "we recommend this new album that is trending" but "this artist is similar to this other one" in the style that the old what.cd site had, with its massive graphed connections from one artist to another based on style (within a genre) of music.

The UI design is just awful for this day and age. It looks like MySpace from 15 years ago.

For example you get to an album page and there's just so much crap. The album and the player should be the main focus but the player is this tiny thing relegated into a corner.
