Usher and Linkin Park take home 2 awards apiece

Ashlee Simpson was able to redeem herself at the Radio Music Awards.
LAS VEGAS (AP) -- This time Ashlee Simpson sang it for real.
We think.
The 19-year-old pop artist was among a slew of stars who played Monday during the 2004 Radio Music Awards at the Aladdin hotel-casino on the Las Vegas Strip.
Usher and Linkin Park took home two honors each. Usher won Hip-Hop Artist of the Year and Hip-Hop Song of the Year. Linkin Park grabbed the Alternative Rock Song of the Year and Rock Artist of the Year.
Destiny's Child opened the celebrity-laden show, wowing a screaming audience with "Lose My Breath."
Train, Chingy, Elton John, Tim McGraw, Big & amp; Rich, Gretchen Wilson and Alanis Morissette also dazzled the crowd with their performances.
But whether she liked it or not, Simpson was at the center of the show thanks to a glitch on "Saturday Night Live" last weekend that revealed she had been lip-synching one of her songs.
It was live
Before she sang "Autobiography" off her hit album, host Carson Daly reassured Monday's audience they were getting a live performance.
"Live, yes live," he said.
When Simpson's band started playing, the younger sister of pop starlet Jessica Simpson screamed, "It's the wrong song." Seconds later, she told a stunned theater filled with hundreds of people that she was "only kidding."
Later in the evening, she told Daly in an off-stage interview that acid reflux disease had made her lose her voice four hours before her "SNL" appearances.
She didn't seem concerned about her slip up.
"You move on," Simpson said. "Things happen."
The two-hour show was broadcast live on NBC. The nominees in each category were based on radio's top-playing songs. Radio program and music directors nationwide voted on the winners.
