I'd be surprised if it was higher.
The German boxart will look pretty bad as they have to move the logo to the right:
(still the provisional box)
I recently got a Bitches Brew 4 disc cd set in book form, and was kind of not happy there was the triangular logo for mature audiences on there. I was even more weirded out with the fact there is hardly any talking on the DVD they have in there, and apparently the logo is from the name of the title of the fucking CD LMAO. It's not huge or anything, but it's definitely distracting.
I also just bought, and then sent back, Pearl Jam's 20 Bluray which came from Europe and had 6 stickers, that would not really come off, plastered all over the cover.
Like what and the fuck are these people thinking with these ratings systems interfering with the actual cover art. Europe is the FUCKING WORST about this.
I once got a Roots CD and it happened to be from Europe. I promptly sent it back because the parental advisory label in the US actually looks cool. The one from Europe looks completely idiotic.
Don't get me wrong I still import a lot of CDs and stuff but man these labels are OUT OF CONTROL.
