In any creative discipline, everyone has their own taste. What makes a piece of music good or bad is entirely subjective: one man's trash is another man's treasure, as the old saying goes. This doesn't only apply to the style or vibe of a piece of music, though, but also to the way a song is produced, mixed and mastered.
Without getting too philosophical, this begs the question: Is there really such thing as a "bad" mix? We’re not entirely sure, although there are, of course, some generally accepted mixing norms that are widely followed to ensure that music is pleasing to the majority of listeners.
