It doesn't INHERENTLY matter, and normally it wouldn't matter, it only matters because these are the rules that we all agreed to. I know, I've broken some myself either on purpose (for a good reason) or accidentally. And I got "smooshed" for it.
Anywho, I can't wait for the artwork, and hope it is simply the majesty logo and "Dream Theater" on it, in some sort of unique color scheme so we can call it it's own {color} Album, since the Black Album and the White Album are taken.
