@ Kyla:

Lots of artists signed to major labels are forced to do the more marketable type of music that their label wishes them to do at the start of their career, it's when they acquire commercial success that they finally have the clout to have a say in their image and sound. Perhaps pop-rock is what the real Pink is, and the R&B style is what L.A. Reid wanted her to be. And she didn't jump on any "bandwagon", she went the rocker route when virtually no other mainstream female performer was doing it!
