Interesting watch. So it wasnt my ears at all when i thought Madonna sounded awful.

Just have watched this and I'm shocked that even someone like Beyonce could lip sync! I'm not surprised by Britney Spears, so I suppose that explains One Directions success then!
I thought that was just too bad during the clip of Justin Bieber dropping his mike, and the singing continuing, which obviously showed him up completely!

This is exactly why you need a marketable image - singing is not the most important thing anymore sadly - it's all a good beat and style
