5. 'Titanium' (cover by Minute Taker)

David Guetta first got Mary J Blige to do the vocals on this but the released version (co-written by Sia) ended up with Sia singing the whole thing. You've all heard it a million times so, instead, here's a very good cover version by Minute Taker, a singer-songwriter from Manchester whom we've championed here on The 405 quite a lot in the past 18 months.
