The answer to this is obvious because Unapologetic's singles were huge (well some of em at least) but it doesn't change the fact that BEYONCÉ is a better album by far.
Honestly... Unapologetic
I prefer the B5 singles, but Diamonds was massive, and Stay did great too. Drunk in Love is the only one that has touched their impact #surfboart #watermelon, and Partition is the only other single the GP is currently aware of because of the video...
