The song was featured in the films Night at the Museum: Secret of the Tomb, Pitch Perfect 2, Vacation, Sisters, in the TV shows Red Band Society, Hawaii Five-0, and in the teaser trailer for the 2018 animated film Teen Titans Go!

According to group member Pete Kirtley, the song is about "not giving up, even though the path ahead sometimes seems impossible and unreachable".

He's moved from the abrasively chilly trance of 2009's Kaleidoscope to embrace pianos and guitars, a warm sound like the 4 a.m. version of Taylor Swift or Coldplay.

He's a consummate crowd-pleaser, but he's best when he gets weird: The warped grind of "Echoes" is a standout; "Wasted" might be one of 2014's best country songs.

Starting in 2015, the songs Footprints, Rocky, and Red Lights are featured as one of the shows for the Fountains of Bellagio.
