A 6th week for Dark Horse at #1 has like a really really slim chance. Things are already very close as it is for a 5th week. If you look at Pharrell's airplay numbers, he's really just closing that gap fast and he's starting to pick up on streaming as well, not to mention the sales gap getting even bigger and bigger. Despite that I think Dark Horse will continue to have good longevity at #2 for at least a month until John Legend catches up on her on all chart components.
Talk Dirty has stalled so much.

Has the celebrity video thing come out yet?
Wait, 6.9 million video streams for Dark Horse.
