I get your skepticism here Diddy but the "announcement" earlier this year that didn't happen make me thing this is even more real. This isn't just blinkitalia posting stupid shit, there are too many weird coincidences happening this time. In my mind at least.
I actually don't think this is true. Especially in the "PUNX" genres.
I mean look at blink, Mark mostly sounds pretty good, but sometimes struggles mightily with certain songs/parts. It'd sound way better if he had assistance.
