I can allready see it. If the vocals are polished for a official release, the You-Tubers will be calling it out comparing it with the un-official leaks from the raw version. For me personally, I don't care. I agree with Bosk, I would rather it sound better with a good replay value and share-ability with friends that come over and watch it with me.
It wouldn't be fair to JLB if he had to be embarrassed about any cringeworthy moments. It needs his stamp of approval.
