* by Tori Amos

I never got the hang of Tori until Boys for Pele came out... to this day it's my favourite album of hers.

* by Christina Aguilera

I initially wrote Christina off as mindless bubblegum pop, but it turns out she actually has some skill in that blonde head of hers.

* by U2

I used to think U2 were geniuses, but it's actually Brian Eno who's the genius. U2 have gotten stuck in a stylistic rut the likes of which they will never escape, sadly.
