I'm not sure, honestly. I saw a couple of people's avatars with the lines in the background... then I got one with straight blue.
Then, also, I was in Target, and through the clear CD case spine, I could see that some had this white block printed there, but I couldn't see the rest because it was under the pamphlet, and some didn't. Any clue on this as well?
I got one at Target... but I notice that the cover isn't the same as others, mine doesn't have the lines in the background. Why is that? (I'm new, so I'm sorry if it was discussed already!)
