    Of Monsters and Men - "Little Talks"

    The success of "Little Talks" stems from its core song structure which relies on, you guessed it, I-V-vi-IV. Written in the key of D-flat major, that chord progression is inescapable and varies little throughout the song. It's really no surprise the song's become a radio mainstay and is fast approaching 100 million YouTube views.
