WATCH: This Imagine Dragons & Khalid Mashup is DOPE!

Imagine Dragons is ALL over the place.. like EVERYwhere right now... their arguably biggest song to date, "Thunder," is a freakin SMASH. 

ALSO, Khalid is pretty much a new-comer onto the scene, but was nominated for a GRAMMY and is only 20 years old! His song "Young, Dumb & Broke" makes a GREAT treadmill song! haha

Some brilliant soul took the time to do a MASHUP between these two songs and it's honestly one of the best mashups I've heard in a HOT minute!
