Disney is known for its extensive musical collection and memorable composers. One of the major points of hype for the studio's animated films during the Disney Renaissance of the 1980s and 1990s was the release of a whole new set of songs. Audiences almost always expected to go home humming the tunes. Disney knew the melodies had become a main reason people flocked to the theaters to see its latest releases. By the time the mid-1990s rolled around, the company was contracting major artists like Elton John (The Lion King) and Phil Collins (Tarzan and Brother Bear) to the list of heavyweight songwriting partners.
