For those of you in the UK or who have access to the BBC iPlayer Mark Radcliffe presents a countdown of the ten songs which have earned the most money of all time - ten classic songs each with an extraordinary story behind them.
Its an interesting hour and a half and Im sure you will have heard every song they have chosen. Some of you may also start to think differently on the all too familiar dream of "Getting Signed" when you see where all the money actually goes.

Which track would you guess is the top earner ?
