The unauthorized replacing of the original soundtrack of an audiovisual recording, such as a movie or television show, with one designed to substantially alter the original plot and/or characters.
The term "trackjacking" is derived from a conjunction of the phrase “soundtrack hijacking,” and is intended to convey the idea of unauthorized usurpation.
A trackjack is easily distinguishable from a mashup. A mashup combines two preexisting works in a creative way to make a new product through selection and arrangment. A trackjacker adds their own new content to a preexisting work while leaving the preexisting work substantially unaltered.
My friends and I got together last weekend to do some trackjacking. We recorded new dialogue to "My Little Pony: Princess Promenade." You should rent the movie, then watch it on mute while listening to our trackjack on your iPod.
Examples of trackjacking include:
Brad Neely's "Wizard People, Dear Reader"
My Way Entertainment's "The Juggernaut Bitch!!"
Fensler Films' "G.I. Joe PSAs"
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
