Formation

Beyoncé is too hard to spell, so Imma use B, aight?

B made possibly one of the the best tracks I've heard. There are some weird parts, but it's still great nonetheless:

Refrain:
I think that B has a bad rap voice. At the beginning of the refrain, at least. She sounds depressed and sad. I would give this a lower score, but the end of the refrain makes up for it. This is energy. The delivery is clean, and rough. The rapping in between is the best part of this, by far! The singing at the end is exquisite, to say the least.
Score: 7/10

Interlude:
Simple interlude. Kind of funny. Mostly awesome.
Score: 9/10

Chorus:
Possibly one of the best choruses ever, B makes this long chorus have impact, and uses wordplay amazingly. Points deducted for having 17 "okays" (with adlibs), and having the chorus be a bit too long.
Score: 8/10

Verse:
Great verse from B. It's simple, repetitive enough to have emphasis, but not to get boring. Short, simple, sweet, to the point. Awesome.
Score: 9/10

Bridge:
Just a copy of the end of the chorus. I'll give it the same score as chorus.
Score: 8/10

Total: 7+9+8+9+8=41/50 which is 84%

Consensus: B just needed more energy in some parts of the track (refrain). And maybe cut down the length of the chorus and the number of "okays."
