Well said, Joe and Scrump.

One thing the computer programmers didn't plan for is the human desire for novelty and innovation. How do you tell a computer to do something it's never heard of before? It can't, but people can.

As an example: I don't know how many times I have seen people comment on the Mudcat that with popular music we hear the same 25-30 tunes over and over. One result of that sad state is the growth of independent music releases as musicians struggle to play what they want to play.
