Most popgirls seem to have atleast 5. Why is it that some have 0 or 1 even after more than a decade in the industry...why is this?

i think years ago it was pretty difficult to earn a grammy....pop girls didn't stand a chance....i don't think Gaga Rihanna or Taylor would earn any grammies in the 90s.....as for Katy....well even now that its easier she hasn't yet earned one cause critics don't respect her....
