TD and it's not even close

Single Ladies impact, album sales and the GRAMMYs (and the tour) is the reason why IASF was bigger than TD

"And it's not even close" ok at this lie

Single Ladies was a viral sensation back in 2008. Its "impact" is highly overrated. I'd say the two eras are about even. Bey had the album sales and tour, Katy had the single success and matched a record held by the biggest legend in pop. Both big eras.

Lol. Irreplaceable was a bigger hit than any of TD's singles tbh.

This might make sense if Irreplaceable was on IASF.

TD by a good margin.

TD

Definitely not bigger than CG or Firework WW.
