Surfing the web I just came across with the original (and first) upload of 'You Know I am No Good' music video (among with the others) on Youtube. It's quite interesting to take a look at it because this video has 22 M of views (and was uploaded 3 years before than the one on Amy Winehouse VEVO account!). For some strange reason, this video was taken down (maybe related to copyright issues) and reactivated recently. Therefore, You Know I Am No Good video on VEVO should have like at least 115 M of views.
Enjoy it!
