“Thunder” is the second single from Imagine Dragons' third album, following “Believer”.

“Thunder” is about not conforming to society’s standards. Dan sings about being told what to do as a child, and that he can’t follow his dreams. In the second verse, he says that he overcame everyone that told him what to do, and achieved his dreams of being on stage.

“Thunder” peaked at #4 on Billboard’s Hot 100, and scored the band their first song to surpass 1,000,000,000 (one billion) views on YouTube.
