Ermmm sure dude - I've released albums before. Granted I've always mixed them myself, but I know I wouldn't leave the choice of MY albums mix up to a bunch of random strangers on the internet.
Honestly, it's insulting to the people who put in time and effort mixing these tracks, only to be put up for public referendum. They were mixing for YOU, not for joe schmoe on the internet. If you like their work, you pay them for it. If you don't, then don't chose to work with them. But don't hold a 'contest' and then put up a poll, that's just stupid.
