Heavydirtysoul

"Heavydirtysoul" is a song written and recorded by American musical duo Twenty One Pilots. The song was released as the sixth and final single from their fourth studio album Blurryface on December 9, 2016; some of the song's lyrics are directly taken from lead singer Tyler Joseph's "Street Poetry", published on Rock Sound's official YouTube channel on August 27, 2013. The music video for "Heavydirtysoul" was released on February 3, 2017, it was directed by Andrew Donoho and shot in the band's hometown, Ohio. It begins with frontman Tyler Joseph sitting in the backseat of a vehicle, driving erratically along a highway. Josh Dun is seen playing drums in the middle of the highway, his drum kit catches fire, but he continues playing anyway; the vehicle that Joseph is in is heading towards Dun, loses one of its wheels just before swerving to miss a head-on collision with him. It's shown that the driver of the vehicle is an unknown figure wearing a black hoodie; the sequence of Joseph driving past Dun is repeated as the car continues to spark from its missing tire.

The vehicle continues to fall apart due to Dun's drumming, when the vehicle loses its roof and its doors, Joseph climbs on top of it and jumps off near Dun as it explodes further in the distance. The duo perform the remainder of the song on the highway during the night, surrounded by the car's flames; the ending of the video shows the sun rising, Joseph, along with the vehicle, back to their original state. The car that's used in the video is a grey Cadillac de Ville sedan; this same car is seen at the beginning of the "Jumpsuit" music video, burnt before once again catching fire. The video for the song has garnered over 110 million views on YouTube as of May 2019. "Heavydirtysoul" peaked at No. 8 on the Hot Rock Songs chart, No. 2 on the Alternative Songs chart, No. 22 on the Mainstream Rock chart, No. 25 on the Bubbling Under Hot 100 Singles chart in the US. The song appears on the soundtracks for the video games WWE 2K16 and Madden NFL 16.
