Swedish House Mafia - Don't You Worry Child

The first time I heard this track, I think I may have teared up. Knowing the boys are definitely taking a break from collaborating together, and will no longer be performing together, makes this final SHM track especially emotional.
At first, it sounded like Coldplay's Chris Martin on vocals. That would have been amazing since SHM repeatedly makes it known how much they want to collaborate with him. However, as the track goes on, it does sound more like John Martin (no relation!) who lent his vocals to SHM's "Save the World."
