What started as a small comment in a Florida Georgia Line interview has now completely come to fruition.
It's The Chainsmokers feat. Florida Georgia Line - "Last Day Alive"
The backstory is that F.G.L. was asked in an interview about who they'd love to collaborate with. They mentioned The Chainsmokers, and a few days later, got a call from them. The rest is history, and this is what we ended up with.
