Everybody gonna say "You, K"

For the past couple of days, I've had Estelle's "American Boy" stuck in my head. I think it may be because I keep thinking "I'm in the UK." And then, Kanye's rap sequence comes into my head; the part where he says "Who killing them in the UK? Everybody gonna say 'You, K'". It's not a very good line but it keeps getting stuck in my head these days.
I decided to YouTube the song and an impressive cover by Sam Sparro came up. In the middle of the song, he does his own little rap; it's entertaining.
Check it out.
