#9 Last Christmas by Wham! 

Best Sing Out Loud Moment: “Last Christmas, I gave you my heart / But the very next day, you gave it away / This year, to save me from tears / I’ll give it to someone special.”
Interesting to Note: Wham! was the only non-black music group to make the list. The song was recorded for charity, where proceeds went to benefit famine relief in Ethiopia.
