Britney isn't relevant anymore (at least for the gp), just like Xtina and Madonna, she should be making music for 30+ years old, not teens. Pop radio won't pay attention to them.
Beyonce and JT are the only artists from her generation than GP still support.
It grew on me.
But when I first heard it, it sounded like an album track and not a single imo. Wasn't up tempo enough, and her vocals weren't good enough to carry a mid/low tempo.
