well i was just re-reading that "most annoying person in metal" thread and interestingly enough, the fact that some people (perhaps most) believe that bands owe us (fans) something came up.
to what extent do they owe us? do they have an obligation to produce the sound that we love? Or are they entitled to produce what they want, how they want, ready for us to judge it?
band success no doubt is driven from fans - however, just like most people who make money - they are serving customers; ie: us. does this make them inhuman, expected to serve our every wish?
do you respect your customers all the time? dont some get on your nerves? wouldnt you like to do what you want, how you want?
plus the amount of people out there who outright rip bands off by merely downloading their music and not buying it is another factor which beggs the question, do they owe us? or do we owe them?
personally i think its somewhere in the middle. it definitely sucks when a band loses its sound to make more cash, (when its probably in abundance anyway) but at the same time, they are just trying to produce music that will sell.
