If you were any doubt that Ke$ha’s a little different from most pop stars, check out her hobbies. In amongst the usual shoe shopping and spa trips, she’s spent the past year variously crafting jewellery from human teeth, rehabilitating lion cubs in Africa and – allegedly – tattooing members of The Flaming Lips at house parties. Professional that she is, she briefly put that extra-curricular craziness to one side to write a sophomore album, reportedly inspired by Iggy Pop’s seminal debut. Now, it’s been a while since we last gave The Idiot a spin, but we’re pretty sure that there wasn’t a great deal of techno-influenced dance-pop involved. Mr Pop does appear on ‘Dirty Love’, though, so maybe the reference isn’t as tenuous as it appears.
