Interestingly, although it got over 9 millions stream from Xmas Day to NYE 2020 that’s not what got it over the line. 1 download = 200 streams and Last Christmas got just over 1500 paid for downloads whereas All I Want For Christmas is You only got just over 700 paid downloads. So for the extra 99p x 800 downloads (roughly £800) spent by Wham fans it made it to number one! Bargain!
Let' hope it regularly makes the number one spot each and every year. Best. Song. Ever.
