Is Imagine Dragons' Radioactive about Lord of the Rings?

I was listening to Radioactive the other day and I started thinking it would make a great theme song for the Battle of the Pelennor fields. Or just the Return of the King in general. 
You know, I can totally imagine this playing after Aragorn's Speech, when they charge. Welcome to a new age meaning Welcome to the Fourth Age.
Okay, maybe it's just me being a LOTR nerd but whatever.
What do you think?
