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"
