Britney is not in the top3 most "heavily debated" girls on ATRL. Again, her biggest hits were pre digital era.
At the end of the day, this was a great list, I enjoyed reading until until that very weak shade. The post went from informative to flamebait. Unnecessary and childish.

Nayer's a girl, underline

There's literally 100 threads a day Britney based or she included. Understandable your anger at the shade, but I know you're smart enough to realize Britney is one he was talking about if Katy/Rih are already on the list - which is weak shade in itself from you.

Yes Britney is talked about on this site a lot but not as much as Bey, Gaga, Katy and Rih. Heck, these days even Lana is more talked about than her.
PS: I'm never bothered by shades. There is nothing to be bothered about, they are either weak or funny.

Womanizer got close with 3 200k+ download weeks. Either way, Miley.

I don't really see as much debate about Katy or Rih. Everyone knows they're both currently successful and get lots of #1s.
While there's a hugely polarizing range of opinions about Britney: is she a legend, or is she a flop? Is her Vegas thing a success, or is it overshadowed by the non-success of BJ? Do fans overrate her success? Is her peak the biggest ever? Can she really lay claim to the title of Madonna's successor? How long was she a success - a decade, half a decade? Is she really considered an artist?
It's always possible it feels that way because being a fan I tend to look at threads about her, giving a confirmation bias.

It wasn't supposed to be "shade." I was just noting surprise, and I wanted to note it in case people asked "But what about her? Did you forget [this hit]?"

Anyway, Problem is now in Say Something territory (6 weeks for a mixed collab, yet not reaching #1).
And Fancy is in Tik Tok territory (7 weeks, with a peak at over 300k).
All About that Bass in Sexy and I Know It territory.
Shake it Off ties I Knew You Were Trouble.
