This is a deleted song from Hercules called, “I Can’t Believe My Heart,” by Meg.
“‘Hercules’ was one of the few films made during the Disney Renaissance of the ’90s that wasn’t structured in a musical format. Most of the songs were sung by a Gospel chorus who also provided backup to Megara’s one song ‘I Won’t Say I’m in Love.’ However, she had a solo song, much slower in tempo, and similar in tone. It’s unclear why it was cut from the film, though perhaps the two songs were too similar since both involve Megara lamenting about being burned by the men in her life. No storyboards are available for this one, but a fan set it to scenes from the finished film that accompany the music perfectly.”
