"I'm So Sorry" is a song by American rock band Imagine Dragons. The song serves as the second promotional single and fourth track from the band's second studio album Smoke + Mirrors (2015). Along with the songs "Hopeless Opus" and "Gold" on Smoke + Mirrors, the song touches upon lead-singer Dan Reynolds' depression struggles.[1] The song has peaked at number 14 on the BillboardHot Rock Songs chart.
The song has been compared to the work of the Black Keys by music critics, with Mikael Wood of the Los Angeles Times comparing the song to the Black Keys' "fuzzy garageblues" sound,[2] Jon Dolan of Rolling Stone describing the song as a "Black Keys-indebted garage-blues grinder",[3] and Stephen Thomas Erlewine of AllMusic calling the song "a Black Keys number stripped of any sense of R&B groove".[4]
The song was sampled for the tracks "The Arrival of Kai", "The Hall of Heroes", "The Legend of Kai", "Po Belongs", "Kai is Closer", "The Battle of Legends", and "The Spirit Realm" in the Kung Fu Panda 3 (soundtrack).
