Some pop songs contain lyrics which describe the steps to a dance. Examples include The Loco-Motion, Time Warp, and Cha Cha Slide.
Is there a specific word for a song of this type?
They are called Fad Dances
"In the early 1970s the disco spawned a succession of dance fads including the Bump, The Hustle, and the YMCA. This continued in the 1980s with the popular song "Walk like an Egyptian", in the 1990s with the "Macarena", in the 2000s with "The Ketchup Song" and in the 2010s with "Gangnam Style". Contemporary sources for dance crazes include music videos and movies."
