Usher, Outkast Big Winners At American Music Awards; Kanye West Robbed By Alex VeigaAssociated Press Writer LOS ANGELES (AP) – R&B sensation Usher won all his show-leading four nominations at the American Music Awards on Sunday, and Atlanta-based rap funksters OutKast went three-for-three during a performance-studded, occasionally censored broadcast ceremony. “Thank you for this moment. Thank you for this year,” Usher said as he picked up his last award of the night. “It’s been amazing.” Usher won for favorite male soul-R&B artist, best pop-rock artist, best pop-rock album and best soul-R&B album for “Confessions,” which sold more than 1 million copies in its debut week. OutKast, the Grammy winners whose album “Speakerboxxx-The Love Below” spawned the mega-hit “Hey Ya!” took home awards for favorite pop-rock band, favorite rap-hip-hop album and best rap-hip-hop group. In his acceptance remarks, OutKast’s Big Boi paid tribute to founding Wu-Tang Clan member O.D.B., who collapsed and died inside a New York recording studio Saturday. The rapper’s cause of death was not immediately clear. “Rest in peace Ol’ Dirty Bastard,” Big Boi said. “We love you.” Soul diva Alicia Keys won favorite female artist in the soul-R&B category, edging out Janet Jackson and Beyonce. Country singer Kenny Chesney said he was surprised to win a publicly voted award for favorite performer. “I really didn’t think anybody was going to beat Usher tonight,” Chesney said. Rapper Jay-Z won favorite male artist in the rap-hip-hop category. Country singer Gretchen Wilson won the best new artist, beating out innovative rap newcomer Kanye West. Backstage, West vented his disappointment over being shut out in all of his three nominations. “I feel I was definitely robbed … I was the best new artist this year,” West said. “I don’t know if I’ll be back at this award show next year.” Nominees were chosen on the basis of record sales, with winners selected by a survey of about 20,000 listeners.
