“I Will Always Love You” by Whitney Houston
Although you may be most familiar with Whitney Houston’s version from her 1992 film “The Bodyguard,” the song was originally written by Dolly Parton. Going by the plot of the movie and its title, the song is often interpreted as being about a romance. However, it was originally written by Parton about moving on from her mentor and music partner, Porter Wagoner. For seven years, Parton performed with singer Porter Wagoner, and even released a dozen albums with him. When she decided to go solo, she wrote the song to say goodbye.
