Whitney Houston - "Exhale (Shoop Shoop)"

The summer of 2016 saw Justin Timberlake debut "Can't Stop the Feeling" in the #1 spot.  This begs the question: how often do songs debut in the #1 spot on the Hot 100?  Actually, not often.  In fact, it's only happened 26 times in the history of the Billboard Hot 100 -- including a record-setting four times in 1995.  That year saw not only Whitney Houston's "Exhale (Shoop Shoop)" debut at #1, but also "You Are Not Alone" by Michael Jackson, "Fantasy" by Mariah Carey, and "One Sweet Day" by Boyz II Men and Mariah Carey.
