When politicians want to confirm how magnificently out of touch they are with the real world, they'll make a comment about current music, probably hip-hop.
Some have complained that rappers are to blame for making teenagers violent, although surely if violence could be caused by music about violence, Tchaikovsky must have caused mayhem with his 1812 Overture. Nineteenth century Europe must have been awash with drive-by cannonings, and soldiers snarling "Prussian mothafuckah".
Even worse are those who try to embrace hip-hop, such as David Cameron, who you expect soon will tell us: "My shadow cabinet crew is well sick and ready to mash up Labour. You get me?"
