Agreeing to disagree is at the heart of the new video from the unlikely duo of Queens of the Stone Age frontman Josh Homme and moody-rock queen PJ Harvey, directed by filmmaker Hal Hartley (Trust). ''It's about two people's confusion over the same idea,'' says Homme. The tune -- the first single off his side project Desert Sessions Volumes 9 & 10 (Oct. 14) -- is sure to thrill fans of Harvey's dark ''Down by the Water'' as well as Queens fans. But the video may be another story. Homme expects MTV won't play it because it's too arty: It's just him and Harvey arguing in a car. Clearly, he hasn't seen Newlyweds.
