As I write this another 88,845,326 tracks need to be downloaded on iTunes until the market leader download store has sold over a ten billion songs. Oh, hang on, now its 88,845,259. And now it's 88,845,173. I'm going to close this counter window, it's distracting. Whoever buys the ten billionth download will get a $10,000 iTunes voucher. So, get your finger ready to click 'buy' in 88,844,987 downloads time.

In a bid to start building some hype ahead of that landmark, Apple last week released details of the top ten tracks downloaded on iTunes since its US launch in 2003. Brace yourself for this. There is a chance this list will make you want to jump out of the nearest window, and then you'll have no chance of winning that ten grand iTunes voucher. OK, here we go, in reverse order, the ten biggest iTunes downloads of all time...
