Uptown Funk was off I-Tunes for part of a day while they were either removing a version or combining the versions. That's why it has that awful estimate from Kworb. I think it sold about 70 k last week, and I think it should get 55 K this week, and UF might actually rebound a little next week since it will be on I-Tunes all week and the Voice is over and done with. Those few hours where UF was there and gone and back again will impact the total this week, because it took until today to get back in the Top 20. There is no second version of UF anymore.
