Of course not. Beyonce has already proved shes an icredible artist and successful. Everything else she releases will simply be because she enjoys making music.
Probably wants to put out a quality album and felt the original version of the album wasn't what she envisioned.
I don't think she'll have anything to worry about with the next album. Adele and Gaga overshadowed 4 and the album wasn't even made that big a big deal (and the poor single choices didn't help it either). I have a feeling Columbia will treat this era a little differently.
Plus she has no real competition right now so what's there to fear?
She's a perfectionist, and so obviously she's not satisfied with the album as it is to release it. I just hope this isn't some "Chinese Democracy" type of mess.
I think so, but only because she's dissatisfied with the songs she made for the album. I'm pretty sure it's just general knowledge now that's she trying to figure out her album's direction.
