The 90's gave us four of the greatest ballads of all-time: Celine Dion's "My Heart Will Go On", Bonnie Raitt's "I Can't Make You Love Me", The Dixie Chicks' "You Were Mine", and Whitney Houston's "I Will Always Love You". All three are flawless. I think my favorite is "I Will Always Love You". That song makes me cry no matter what. I have a lot of personal connections to that song that make it emotional for me. "You Were Mine" is a close second, closely followed by "I Can't Make You Love Me", which is followed by "My Heart Will Go On".
Prince - Diamonds and Pearls (I mean who was even touching Prince with his classical songs)
George Michael - Jesus To A Child
Michael Jackson - You Are Not Alone
