Bruno Mars' Top 10 Songs
9. 2. 'Grenade'
In at number two is the 2010 single which saw Bruno hauling a piano around Los Angeles (surely he could have got a removal man to help him no). Anyway, it takes a further dark twist when he catches the woman he loves with another man and then takes his piano onto the train tracks. It's more powerfu stuff from Bruno and a track that scored him another Grammy nomination.
