This is true, but producers are also assuming, like much of the public, that music is so easy to create (mainly because of computer and sample technology) that they SHOULD pay less and less for it. Or that a kid in highschool could do it just as well as anyone else (did you see that 5 year old play the piano?!?).
But the truth is a job (making music) that use to involve a team of people has now many times been reduced to one guy (the composer) who tries to do it all and get it done in less time than ever before. The appreciation of creating something from nothing (or very little) has taken a nose dive. It’s as if no one can see the difference between a studio movie and a youtube video from someone’s bedroom- but applied to music. I hate to say it, but like in parts of the film industry, things may have to go back to collective unions in order to make the situation livable again.
And most composers, though reluctant, are going to have to look into making it a group effort again. I use to mix for a number of composers years ago, now most of them want to mix themselves or get a kid to do it for less. Rather than bucking the producers they seem to be becoming like them (save the $$$ for me!). It’s a sad state that I’m waiting to see when it breaks down (when composers and producers work their ass off but still get little to no payoff, while corps get the lion share)
