Bruno Mars was the only person to sell over 10m downloads with one track in 2011, according to Music Week.
In fact, the perpetual hat-botherer achieved the feat twice, with 'Just The Way Are' selling 12.5m and 'Grenade' shifting 10.2m 'units' worldwide.
The unspeakably terrible 'The Lazy Song' sold an additional 6.5m, which means with just three songs Mars has sold nearly 30m singles in twelve months.
Well done everyone.
