I think this one is most sincere and heart felt seeing they both came from the MMC in which they were best friends and just coming out the same time and dominating the pop scene in that era.

You listen to what is taking place behind closed doors with Britney and then you understnad how meaningful and strong Christina's fall in line song and video is. She was really exposing the dark side of the industry.
