When an album is up for preorder and they release album tracks before release those that have preordered the album will be charged for the individual track. This is why the songs race up the iTunes chart
Sia (as much as i love her) and that other song thats been artificially inflated up the chart will both fall like rocks soon
and UF will of been hurt by losing its #1 exposure which leaves FFS to take the top spot

Imagine Dragons - Shots 1.0000
Mark Ronson - Uptown Funk (feat. Bruno Mars) 0.6730
Sia - Salted Wound (From The "Fifty Shades of Grey" Sou... 0.5511
Rihanna and Kanye West and Paul McCartney - FourFiveSec... 0.5347
so Rihanna couldnt dethrone Bruno but Imagine Dragons did? How?
Everyone with preexisting album pre-orders for the Imagine Dragons album gets the new track at once, which is why it surged up the chart at once and why it's already nosediving.
