There was an interview with Eno in Wired in 1995 [1] that i still think about sometimes. Amongst other things, he talks about lifting himself to the next meta-level of composition, where he doesn't write music, he writes rules for a box which makes music:

Q: If I could give you a black box that could do anything, what would you have it do?

A: I would love to have a box onto which I could offload choice making. A thing that makes choices about its outputs, and says to itself, This is a good output, reinforce that, or replay it, or feed it back in. I would love to have this machine stand for me. I could program this box to be my particular taste and interest in things.

Q: Why do you want to do that? You have you.

A: Yes, I have me. But I want to be able to sell systems for making my music as well as selling pieces of music. In the future, you won't buy artists' works; you'll buy software that makes original pieces of "their" works, or that recreates their way of looking at things. You could buy a Shostakovich box, or you could buy a Brahms box. You might want some Shostakovich slow-movement-like music to be generated. So then you use that box. Or you could buy a Brian Eno box. So then I would need to put in this box a device that represents my taste for choosing pieces.
