"Fallin,'" the hit single from Keys' debut album "Songs in A Minor," won for record of the year and song of the year, as well as best R&B song. The album won for best R&B album, and Keys won for best new artist and female R&B vocal performance.
"I'd like to dedicate this to just thinking outside the box and not being afraid of who you are no matter what you do,'' said Keys, who tied Lauryn Hill's record for most Grammys by a female artist, set in 1999 for "The Miseducation of Lauryn Hill" -- even though "Songs in A Minor" was not nominated for album of the year.
That honor went to the "O Brother" soundtrack, which picked up five Grammys -- even though country stations across the country gave it the cold shoulder and largely kept it off their playlists. The Recording Academy showed a lot of love for bluegrass music all around -- awarding three prizes to Alison Krauss & Union Station.
"O Brother" also won for best compilation soundtrack album and its producer, T Bone Burnett, was named non-classical producer of the year. Two songs from the album were also singled out.
Ralph Stanley, the 75-year-old bluegrass legend, won for male country vocal performance for "O Death," and Dan Tyminski, Harley Allen and Pat Enright -- The Soggy Bottom Boys -- won for country collaboration with vocals for "I Am a Man of Constant Sorrow."
Burnett also picked up a traditional folk album Grammy for "Down from the Mountain."
Asked backstage to explain the popularity of the "O Brother" soundtrack, Burnett said it isn't that easy.
"Really, this is music for people who like music," he said. "Not everybody does. Music annoys some people. They just don't care for it. But if you do like music, then chances are you like this record."
Alison Krauss & Union Station won for best bluegrass album ("New Favorite") and best country song and Performance by a Duo or Group with Vocal for "The Lucky One."
"This is the music we've loved our whole lives," Krauss told reporters backstage. "It's the most natural thing in the world to be playing it."
Veteran Irish rockers U2 picked up four Grammys -- one more than they took home last year for the same album, "All That You Can't Leave Behind." "Walk On" won for record of the year, "Elevation" won for rock performance by a duo or group with vocals, "Stuck in a Moment You Can't Get Out Of" won for pop performance by a duo or group with vocals and the album won for best rock album.
The single "Beautiful Day" won three Grammys last year -- for record and song of the year and rock performance by a duo or group with vocals.
"Stankonia," by the Atlanta duo OutKast, won for best rap album.
The telecast, originating from the Staples Center, opened with U2 performing their record of the year nominated song, "Walk On."
Host Jon Stewart got his portion of the show started with a gag that tied in post-Sept. 11 anxiety with one of his funnier subjects from the 43rd Grammys -- the controversy over Eminem's anti-gay lyrics and the rapper's duet with openly gay pop icon Elton John.
As Stewart walked under an arch -- part of the set on the Staples Center stage -- he set off a beeping noise and was set upon by "security" personnel who stripped him down to his shorts before they would let him take his mark on the stage.
"Remember when security was tight because Eminem was going to sing with Elton John? Those were the days," joked Stewart.
When Christina Aguilera, Lil' Kim, Mya, Pink and Missy Elliott performed their Grammy-nominated version of LaBelle's 1975 hit "Lady Marmalade" -- from the movie "Moulin Rouge" -- they were joined by a surprise guest, Patti LaBelle herself.

His sister, Janet Jackson, won a Grammy for best dance recording, "All for You."
