If you grew up in the '90s, there's a decent chance you sobbed out your heartaches to the Titanic soundtrack. There's also a decent chance that you shared a slow dance to Celine Dion's chart-topping Titanic song, "My Heart Will Go On."

James Horner, who created the Titanic soundtrack, had a pretty impressive ability to infuse his music with emotion, and his Titanic soundtrack pulses with all the feels:

• Excitement: When the ship sets sail—and there are no icebergs in sight—the music soars along with the characters' sense of possibility.
• Adventure: For example, when Rose and Jack are frolicking together below deck, the music romps as well.
• Romance: When Jack and Rose are frolicking in, er, another way, Horner's score softens.
• Urgency and danger: When the ship's crew spots the iceberg, the music abruptly changes as well, clanging and thundering along as people work together throughout the ship to get her to turn.

In some films, the soundtrack just fades gently into the background, but not in Titanic—music plays a huge role in taking the audience along for the ride, emotionally speaking. Given that the soundtrack was so memorable, it's no surprise that it sold a whopping twenty-seven million copies.

Horner collaborated with Cameron a few times—on Titanic, Aliens, and Avatar—and they were believed to be working together for the Avatar sequels as well.

Unfortunately, Horner died in a plane crash in 2015, so those further collaborations were not to be. The legacy he left behind, though, was pretty, well, titanic (sorry, we had to do it at least once).
