Madonna is the chameleon of pop, constantly reinventing herself so that just when you think you have her sussed she spins off in a completely different direction. Not surprisingly this time round she has changed again, gone is the electro influence of Frenchman Mirwais which has delicately been replaced with the hip hop influence of Timbaland and Pharrell Williams.
This song has obviously been plastered over the radio for the past few weeks and so the fact that it also features Justin Timberlake should come as no surprise. All in all a return to form for Madonna but it leaves us with the unbearing question of just what she will serve up next time round.
