The largest-selling album from a movie songtrack ever, and the #1 album of 1993, and one of the top three largest selling albums of all time, comes from a 1992 film which starred a tremendously popular singer. What is the title?

The 1992 romantic thriller starring Whitney Houston and Kevin Costner produced a soundtrack that became a cultural phenomenon far exceeding the film itself. The album's phenomenal success was driven by Houston's powerhouse vocals on six of its tracks. Selling over 45 million copies worldwide, it remains the best-selling soundtrack album of all time and is consistently ranked among the top-selling albums in any genre, alongside titans like Michael Jackson's "Thriller."

The album's inescapable lead single was Houston's iconic rendition of "I Will Always Love You." While the song is now synonymous with her, it was actually a cover. Country music legend Dolly Parton wrote and first recorded the ballad in 1974. Houston's version transformed it into a global pop and R&B anthem, spending a then-record 14 weeks at number one on the Billboard Hot 100 chart.

The soundtrack's dominance didn't stop there. It also spawned the major hits "I Have Nothing" and "Run to You," both of which earned Academy Award nominations for Best Original Song. This trifecta of massive singles propelled the album to spend 20 non-consecutive weeks atop the Billboard 200 chart, making it the undisputed best-selling album of 1993.
