Whitney Houston, pop music icon and one of the most honored female pop singers of all time, died yesterday afternoon at the age of 48. Members of Houston's entourage found her unconscious in a bathtub at the Beverly Hilton Hotel. She was pronounced dead at 3:55 p.m.

Houston's powerful voice and ability to turn singles into smash hits earned her the nickname Queen of Pop. During her storied career, Houston won two Emmy Awards, six Grammy Awards, 30 Billboard Music Awards and 22 American Music Awards.

As a tribute to her outstanding career, we count down some of Whitney Houston's greatest singles of all time:

1. I Will Always Love You

The most famous track from the soundtrack to the movie The Bodyguard was also Houston's greatest single. I Will Always Love You spent 14 weeks at the top of the U.S. Billboard 100 charts and is still regarded as Houston's greatest success in the recording studio.

2. The Greatest Love of All

One of Houston's greatest accomplishments as a singer came on her debut, self-titled album. The single The Greatest Love of All was one of Houston's most commercially successful singles until the release of The Bodyguard soundtrack.

3. I'm Every Woman

Though the song was originally released by Chaka Khan in 1978, Houston's version of I'm Every Woman, released in 1992, was a smash hit. Houston sang backup on Khan's version, which makes the single even more important to the career of the famous singer.

4. I Wanna Dance With Somebody

Houston's second album Whitney rallied off of the success of her well-received self-titled debut album. I Wanna Dance With Somebody was the first single off of Houston's second album and it won the Grammy Award for Best Female Pop Vocal Performance in 1988.

5. It's Not Right But It's Okay

From her fourth studio album, My Love Is Your Love, came another classic song from the talented songstress. It's Not Right But It's Okay cemented Houston as one of the greatest singers of all time. It carried her success deep into the late 1990s.
