Imagine Dragons take us back to the 60's and even the moon in their just released music video for "On Top of the World." It's from their debut album, Night Visions, and follows in the success of "It's Time" and "Radioactive." 

It'll take a few views to catch all the layers and references in the video, including anagrams, conspiracy theories, nods to movies, and minor changes in the details. There are even a few cameos!

How many did you notice?
