alt Hacker NewsI'd say painting is quite a different business model than making music. There are different channels, people nowadays don't understand the value of music because they "have" everything on Spotify/Apple Music/whatever and there must be a huge tech behind you to sell good quality of sound. You also can't make your own CD (yes you can, but will it work with a CDR recorder?) and sell it progressively for $100 then for $500...
Paintings are really different kind of animal.
Music, unfortunately, has a very different business model not just because of the difference in medium, but because it's copyable.
You can share a photograph of a painting, but it's, just, not the painting. A rip of a CD is nearly identical experientially.
There are many who, however, sell tapes, MiniDiscs, SD cards and other obscure formats with a small but serious following.
