1. Grammy gold. Houston burst onto the music scene in a big way -- her self-titled 1985 debut album earned her four Grammy nominations, including album of the year, and one win (best female pop vocal performance for "Saving All My Love for You.") Her debut also scored spots on Rolling Stone's 500 Greatest Albums of All Time and on The Rock & Roll Hall Of Fame's Definitive 200 list.
2. This magic moment. The success of Houston's 1987 world tour, "The Moment of Truth," made her No. 8 on Forbes' list of the top ten highest-earning entertainers that year -- the magazine estimated her earnings at $44 million.
3. And everyone will always remember this song. Houston's breath-defying chorus makes it hard not to. "I Will Always Love You," the theme song to "The Bodyguard" broke records worldwide and rocketed to No. 1 on the music charts of just about every country.
4. Fans look to Houston again. After seven years away from the music scene, in August 2009, Houston dropped her seventh studio album, "I Look to You." It sold 304,000 copies in its first seven days on the market, sending Houston back to the top of the charts and giving her the best debut week of her career.
5. Road to Redemption. Houston used the success of "I Look to You" to launch her "Nothing but Love" world tour, going on now. Though some say Houston's signature voice shows the stress of her ups and downs, she's soldiered on, putting on shows in Asia, Australia and Europe despite fans and critics who've panned her performance.
