Whose next era will be bigger?
Now that Beyonce is finished with recording her album and is rapping up her video anthology, the announcement to her next era is imminent, and will likely begin very close to Britney's new era.
Whose do you think will be more successful?
Britney for sure. Beyonce's hype is dead. The Super Bowl was huge, and then nothing for 6 months. No first single, album, etc.
On the other hand, Britney's new music is shaping up to be EXACTLY what people have been wanting her to release. The hype is pretty big. X Factor gave her a lot of hype, so did the smash Scream & Shout.
