THIS IS A HUGE MISTAKE! Christina has never been a huge collaborator, so to place two ridiculous urban acts on the "teaser" single, paired with production from the pretentious, over rated, Kanye West, is a HUGE mistake. why is Christina so hellbent on ruining her legacy. she need not water her sound down with a bunch of tribal, drum bullshit. PLEASE CHRISTINA... just team up with the producers and songwriters who collaborated to create your only masterpiece -- STRIPPED.
