Bandcamp has served me well for many years, but I don't use it anymore.
I would really like to see something like Castopod [0], but for artists! Spinning up a website where you showcase and sell your music should (and could!) be as easy as using Wordpress, either via a subscription or self-hosted – on your own domain.
Being plugged into the Fediverse makes it much easier to interact with fans and build a connection with your audience. It also makes it easy for people to share and talk about a track or and album. None of this requires that you tie yourself to yet another VC-funded startup and a closed garden.
Maybe someone is building something like this already, that I am not aware of?
