Bingo. The girls want both Rihanna and Britney to be more involved than they are. They don't realize those girls are good BECAUSE they're not involved.
!
And I can say that as a former long-term Britney stan that I always wanted her to get involved with her music and have her write and have then lay off the auto-tune. It's only now (looking back) that I realize all of that is why she was great.
You're delusional if you think this is Britney's most personal or most involved album. BJ is the exact opposite of that. Don't let the writing credits fool ya.
