I was definitely not harsh enough with my rates tbh, especially for the singles. I gave out way too many 10s. For the longest time all that I listened to of Britney were the Single Collection and Femme Fatale though so any songs on those have more of a nostalgia factor than the other stuff.
But the flawless album track from her debut, Deep In My Heart, got my 11 to make up for how long it took me to become a proper stan.
