I can't think of any at the moment, I'll have to think about it, but I hate it when artists put these big ass white borders around their album covers because on my iPod Classic, the album artwork looks disproportionate compared to the other ones and it bothers me so much.
This isn't the worst, but I didn't like the ARTPOP cover at first. It's grown on me a little, but I still don't like it. She had amazing covers for The Fame and The Fame Monster, and I didn't mind the Born This Way cover either. I didn't like the whole motorcycle body thing, but the color scheme wasn't bad; black and white work for her, and I think making it all black and white except for the red lipstick was really epic. The ARTPOP cover was utter chaos, though.
The cover for Talk That Talk was a little boring, too (both standard and deluxe). I just thought Rihanna could've done better. She usually has much better album covers.
