So Britney's not singing in the chorus of Passenger and maybe not the second cerse of Body Ache,
but stop saying "She's not singing on most of the album

"
She IS singing on MOST of the Album
You can hear her on Perfume, Don't Cry, Alien, Chilling With You, Tik Tik Boom, etc
She may not be the best vocalist out there, but spreading lies like "50% of the album is not her" is just cruel.
Give her some credit.
Bye.
