All of Britney Jean is beneath Britney, even aside from the vocal fuckery. It's an album of scraps. It was incredibly stupid of her team to push so hard to release it, though as others have said, they obviously didn't care about anything but cashing checks. But even from a business perspective, it's dumb. It hurt her brand. She was still one of the biggest artists on the planet at that point. Over the previous 5 years, she had racked up 8 top 10 hits in the US, including a handful of #1s. Vegas would have been a success with or without an album to promote it. And I'd argue that the album did more harm than good in that sense, because so many fans were turned off, and it was her first album that casuals truly didn't get behind. Rather than stringing an album together, they could have found one or two great singles, a big feature... anything else to keep her name out there. They could have easily bought time and waited until late 2014 to release an album to promote the extension of the residency. It's depressing to think how much damage they did to her legacy as an artist with that release.
