Newsround's website reports that Justin Timerlake's song SexyBack has taken top download spot in this week's chart.
Here's the video. But why not sing along too? This is how it starts:
I'm bringing sexy back
Them other boys don't know how to act
I think you're special what's behind your back
So turn around and I'll pick up the slack.
Take em' to the bridge
You see these shackles
Baby I'm your slave
I'll let you whip me if I misbehave
It's just that no one makes me feel this way
As for the other verses, well .....
