New music: George Michael - True Faith

The thing about using Auto-Tune is that it can mask a slight vocal weakness , or add a sudden sense of excitement to a line when used sparingly. It's not entirely clear, therefore, why George Michael – he of the soulful, velvet croon – has decided to smother his cover of New Order's True Faith with lashings of effects (some have wondered if it's all James Blake's fault ). Weirdly, it's not been done to enhance a high-octane, lose-your-mind-at-3am belter, but instead a dreary run through a song that now sounds like it's being performed by a depressed dalek. Of course, it's all for a good cause, but is it the worst "non-comedy" charity single of all time? Is it even worse than this?
