The song also features no rapping at all, something that was used in Papa Roach's previous singles.  The video is performance-based, showing the band playing in a Stock Exchange Hall with references filled with fans (including sexual imagery which led the band's lead singer Jacoby Shaddix to describe the video as "stocks and bondage" in an MTV2 interview).  It was directed by Motion Theory.  The song is also the former theme song for "WWE Tough Enough".  It was featured in the video game "MX vs. ATV Unleashed" in 2005.  A "clean" remix of the song called "Getting Away With... (Gran Turismo 4 Vrenna/Walsh Remix)" was featured in "Gran Turismo 4"; it was a bit faster, had the heavily distorted guitars toned down, and had a backing whisper of the words "getting away" instead of ". . with murder".
