No, if you paid attention you would know that MusicTalker and I saw that Billboard made a dumb math mistake, as this week they said All of Me beat Happy by about 1% last week (rather than 0.01%).
The difference was about 12k copies to get Problem to #1.
1. All Of Me = (4-8% of lead)
2. Fancy +1
3. Happy -1
4. Problem =
5. Turn Down For What +1
6. Dark Horse -1
7. Talk Dirty =
8. Not A Bad Thing =
9. Summer +5
10. Ain't It Fun =
11. Let It Go -2
12. Pompeii -1
13. Am I Wrong +5
14. Sing +1
15. Best Day Of My Life -2
16. Loyal -4
17. Love Never Felt So Good +5
18. Wiggle +6
19. Play It Again =
20. Me And My Broken Heart -4
It deserves to stay glued to the T10 until it looks like there could be another song to replace it as the only great one in the T10. Should only be a few months from now...
