Can't get this song out of my head!

Well, yesterday I heard this song, a song which is very popular I think, at least in my country

The only thing I remember is that the chorus says:

"I can't figure it out, no I can't figure it out.."

Can't remember more... A guy sings this song.
Can anyone help me?

Try "I Can't Figure it Out" by Cnx Anti-Social
