The way the delivery format shapes the music is something I've always been interested in, and I don't it's inherently inauthentic that artists have often used that and flourished as a result. A 7-inch 45 mitigates towards a certain sort of listening and a certain sort of music. A 12-inch 33 to another sort. A C90 to another, and a CD to something slightly different too. Streaming fits in there somewhere as a delivery mode with its own listening experience. Not sure where I'm going with this...
