Concerning my previous post I will now go Hitler on your asses and pronounce a universal rule to this tribute:
Since mixing is done separately per team, I will announce a judging team (including myself) which will have to approve the mix as acceptable enough to be part of the tribute, if a mix is not approved, it will be given the chance to fix, get someone else to mix or whatever, but if the problem turns out to be the source tracks themselves then the song will most likely be ruled out of the tribute, for starting again would be too much, plus if it's the same members they will most likely end up having the same problems with their source tracks cause they'd use the same equipment to record.
