I know the name of the band but not their music. I checked that song and I don't think I've ever heard it but it has 1.2 billion views on Youtube so ...
Haha I first learned of them from YouTube (when they tried to appeal to the hipster crowd) but now only hear them because of the TV (football commercials) and the rare cases I'm directly exposed to commercial FM radio. That is, when it isn't a classic rock (The Doors and Warrant) or "new" classic rock (RHCP and Linkin Park) station that some gas station or family-friendly bar/grill least-common-denomitored their way to putting on the speakers.
My Mom is the only person I know who admits to liking them. We tried to get her Spotify but she wasn't interested.
One day, very soon, the Imagine Dragons will be considered classic rock, but commercial radio will have long bit the dust and there won't be any classic rock stations left to call them it.
