Yeah, I think it's a strained metaphor at some points, but I don't think the intermediate information is all like the stuff you don't share when you're coding. I'd love to see the process, love to see alternative imagined possibilities for a piece of music/art, love to hear recorded sound clips before they were compiled/edited/effected/processed/mixed, etc.

Sure, there's some information that many people wouldn't use. But tons of valuable intermediate steps. And it wouldn't have to be any more confusing that a git log is, right? Don't have to look backwards if you don't want to. Or you don't have to use all the source files if you don't want to.

But there's still lots more information that would be the "source."
