One can say (and measure, and hear) with certainly that mastering X is 'smiley faced' compared to mastering Y, but one is limited to speculating on *why* that is.
The converse would be that all the other labels are all colluding to employ a frowny face unless it just happened to be done independently by chance. Of course this is still assuming that what you're crying "lore" is actually reality: that people are claiming that most MFSL releases have a "typical sound" and that is regardless of who has walked trough the doors over their history.
It's a pedantic point but I was not sure it was being fully acknowledged here. Has it been now or will it appear to be conveniently overlooked once again?
Love when you get all pissy like this. <smooches>
