yeah its not it, i already looked it up, its a guy singing.

If it's a guy singing the song, try "Jesus is Just Alright with Me" by The Doobie Brothers.

that wasnt it, its a song thats only a year or two old

You can't get more "du - du du - du du" than:
Lou Reed - Walk On The Wild Side

It's a pretty old song, but give it a shot.

That song is like Dinosaur age.
I thought he said , its only a year or two old.
