Beyoncé hasn't been down with the whole pop/mainstream single success thing for a couple of years now, shes going through some sort of mental phase idk.
Shes more than capable of releasing songs cross format, she tha crossover queen - shes turned lots of urban smashes into mainstream smashes before.
This era though: Drunk In Love went to pop 4 weeks too late, after if had killed XO. Pretty Hurts never went to pop. It was a mess, it is what it is.
7/11 will probably stay on urban, she might post something about it on Facebook. I'd love for a all format single release.. but..
maybe next era she'll do some normal single releases, maybe she'll drop the album by carrier pigeon - like who really knows with this woman
