My clear second place favorite is Greatest Love of All. If a person isn't old enough to remember when this song was actually out, they may not realize Greatest Love of All was magic in the mid-80s. It was the b-side to You Give Good Love and was never intended to be a single. Heavy radio play forced Arista to release the song, and it soared all the way to #1 and stayed there for three weeks, the longest reign at the top for any of Whitney's singles prior to I Will Always Love You.
