"With the advent of sound technology in cinema, Hollywood began to not only include music in motion pictures, but also to make films in which the music helps tell the story. To determine the best & worst musical movies of all time, 24/7 Wall St. created an index based on each film's Rotten Tomatoes average critic rating, Rotten Tomatoes average audience rating, and Internet Movie Database average user rating. To be considered, each film needed to have at least 10,000 total user ratings between IMDb & Rotten Tomatoes and 10 approved Tomatometer critic reviews. The "best" films (#26-50) had to have been classified as a musical or music film by IMDb and all the "worst" films (#1-25) fell only under musical. Due to placement restrictions and methodology, many beloved musicals such as "Grease," "Hello, Dolly!" and "The Sound of Music" are absent from the list. While these are no doubt great films, they fall behind a number of other titles in the eyes of the voting public." - 247wallst.com
