who defines selling your soul anyway?/???
Yeah...I think people tend to get pretty bloody precious about money and art. What the heck is wrong with doing art for money? It's still creative, it's still art. What's wrong with giving people what they want i.e. selling out? Someone's getting entertained, somebody else is getting paid.

Perhaps it's confusing the emotions that the music inspires by listening with it with the process of creation itself. It's possible to create something beautiful and magical for completely mercenary and cynical reasons, such as wanting to eat. Maybe it's like sausages and laws; those who like them shouldn't see how they were made.

I guess fans of music don't like the idea of it being just another service industry.

Daft Punk is an example I think I've referred to on this board on one occasion before, but he/they are an excellent point in case for how selling out can work:
1) Admitted in interviews that he actually doesn't like the disco house stuff he does, would much rather be DJing hard techno, but "it's the only thing I'm good at."
2) Process of creation often consists of borrowing big loops of material largely unaltered. Robot Rock is a good example - a listen to the original track it came from puts things in perspective (and disappointed a few people who compared the two for that matter).

So their attitude towards their own work and the process of creation itself could be described as cynical - should Daft Punk not exist?
