Tell everybody, tell everybody Brothers, sisters, the ending is coming
Some versions of Night Visions use this as the last track.
Grief Song: The singer of "Clouds" apparently had his heart broken, and consequently proclaims that he wants to die. He changes his mind after the third chorus, but still acknowledges the mortality of man. Additionally, said chorus says something about "prisoners" in London waiting "for their turn to be dead."
Heel Realization: One interpretation of "The River" explains that the singer has realized his own selfishness, and decided to perform a spiritual cleansing.
Hidden Track: "Rocks", at the end of "Nothing Left To Say", begins after a two-and-a-half minute outro and fifteen seconds of silence. Even though the name is in the track title, you'd be forgiven for thinking the track didn't exist.
Humans Are Bastards: In "Demons", the line "No matter what we breed / We still are made of greed" implies that basic human selfishness will always be present, no matter how you teach the next generation.
I Am the Band: Dan Reynolds, given as he's now the only original member left.
"I Need a Minute," the first song from the group's first EP, sounds like a peppy dance song. However, the first verse goes like so:
Welcome to the land of fire I hope you brought the right attire The crippled man is waiting at the door He said "your eyes are much too bright" The things you say are never right The sins of all the world lie on your head
"On Top Of The World" has a perky instrumental for a songs who's lyrics are about saying "I Love You" before it's too late.
Dan Reynolds admittedly thought showing a world-shattering apocalypse in the music video for "Radioactive" would seem too predictable, so how does it cover the song's themes of empowerment instead? It tells the story of a young woman who rescues Imagine Dragons from Lou Diamond Phillips, with help from her teddy bear, who slays a puppet monster.
Possibly bearing even less relevance to its song, "On Top of the World" has a video in which the band visits The Sixties and televises a staged moon landing.
Mondegreen: Some songs fall victim to this, requiring Dan Reynolds to Tweet fans the correct lyrics. For at least one tune, "Destination", he admitted considering officially changing the words to match the misheard version ("I think a little 'bout a lot/I reach a verdict" —> "I think a little 'bout a lot/I'm introverted").
In Night Visions, "Bleeding Out" has very dark lyrics (see above), but transitions into the lighter "Underdog", which is both faster and in a major key.
Same with "Demons" followed by "On Top of the World", on both Continued Silence and Night Visions.
Moon Landing Hoax: The video for "On Top Of The World" eventually reveals that the Apollo 11 Moon Landing was filmed in a stage, with Imagine Dragons as the astronauts, Stanley Kubrick as the director, and Richard Nixon watching next to Kubrick. After the "success" of the landing, the stage is swarmed by fangirls who listen to the band perform.
