The Emperor's New Groove was one of the first Disney films after 1999's Tarzan that was not a traditional musical, but only featured a few minor songs. The project was originally intended to be a musical film and many songs cut from the film as the plot changed are included in the soundtrack.
The Sweatbox, which has been almost entirely buried and forgotten by Disney...follows the production of the film from phase 1 as part of the deal made with Sting to write the film's soundtrack (a soundtrack which was left almost entirely on the cutting room floor save for the song which cuts awkwardly in at the start of the credits).
