Whitney Houston's Grammy-winning smash I Will Always Love You is the fourth song from the 1990s - and the first solo track from the decade - to join YouTube's billion-views club.
Originally written and recorded by Dolly Parton in 1973, the song was recorded and released by Houston in 1992. The Houston version of I Will Always Love You topped the charts in the early part of that decade after it was featured in The Bodyguard, in which Houston co-starred with Kevin Costner. Houston's rendition spent 14 weeks at No.1 on the Billboard Hot 100 and is one of the bestselling singles of all time.
