It's #1 on Itunes already!!!
and #3 on US itunes
Rudimental looked like they would take the #1 on Sunday, but according to the Itunes popularity bars, DF are going to be unstoppable. It is also the fastest single to hit #1 on Itunes in a couple of years I heard. (excluding James Arthur maybe).
Really good song. The disco/funk just reminds me of a mix of the 1970s-early 90s music.
