I can't say I'm overly happy to watch Maria Diamandis morph slowly into Katy Perry but the hugely poppy 'Oh No!' is, at the very least, an irresistible step in the wrong direction - not least because the accompanying music video ironically echoes Marina's idea that "Real life has no appeal". Best of all, the Welsh lass has resisted the vocoder monster for another four minutes. Maz, you’ve got another candy-coloured hit on your hands.
