The blockbuster album, buoyed by Céline Dion's megahit, is one of just six soundtracks to rule the annual recap.
The records set by James Cameron's Titanic weren't limited to the box office.
Released Dec. 19, 1997, the movie, starring Leonardo DiCaprio and Kate Winslet, became the first U.S. film to gross over $1 billion worldwide.
The movie's soundtrack achieved rarefied success, as well. The LP topped the Billboard 200 on Jan. 24, 1998, and spent 16 weeks at No. 1 – an achievement that put it at the top of the year-end Billboard 200 ranking. At the time, Titanic was one of only five soundtracks to claim that distinction. The first four: West Side Story (1963), Mary Poppins (1965), Saturday Night Fever (1978) and Whitney Houston's The Bodyguard (1993). Only Frozen has led the year-end list since, in 2014.
