cant find the song.....

hey guys, i heard this song on my brother's computer the other day, and i really liked it, but the computer is now broken and i cant remember the name of the song. i can't remember any specific lyrics either, but its a pretty unique song - its sort of dancey, and instead of a melody it has what sounds like a guy ringing up a radio station asking about a song he heard in a club, and then he says 'it went like this' and he "dun dun dun"s the melody for the rest of the song. its pretty short, but i still like it :P

any ideas?

cant fin a song where the video is like a casting, theres a clown involve in the casting.... its a pop song ...
