Question

why the chainsmokers composed their new song ""THE SICK ??"".......story behind the song.....

Answer 1

The chainsmokers are being questioned by the media and press some of the things that shouldn't be.
They are belittled sometimes.
This is why they made "You owe me"
"Sick boy" to show that they are much more stronger than people think them to be.
They look quite tired after such a huge success of closer and something like this.
