Usually among Britney fans/ATRL in general, the In The Zone era is described as Britney's peak (don't even try to act like it isn't). I'm curious as to why. From quick research, anyone can see that the tour was a complete failure, the era produced only one moderate hit with zero recurrent airplay (Toxic), and mediocre album sales for its time. Why is In The Zone considered Britney's peak?
This isn't meant to insult Britney, BTW. I completely recognize her impact and see that she has several huge eras, I just feel that the ITZ era isn't the best representation of this.
