It's like some forms of metal and punk, being raw is part of the appeal. When most of your songs feature long interludes of "mud"-induced rambling, it's not that important than your prison-phone vocals sound pristine.
Aesthetically, I understand what you're saying. I like muddy stuff, but this is just poorly mixed IMO. Not like in an audiophile "but the compression!" way or something, it just sounds like garbage.
