Would also love Substack to simply build a better Bandcamp* in order to fulfill the prophecy:

Bandcamp : Spotify :: Substack : Bandcamp

(n.b. have you seen the terms of service over at bandcamp lately; if not, a quick Find Text for the word “exploit” is illuminating 🏴‍☠️)

* All we need is file hosting, album pages, basic playlist functionality atop the existing music player, and stripe integration for the first MVP.
