Taylor Swift took the high road as she won six American Music Awards on Sunday to surpass Michael Jackson's record, avoiding any direct mention of a bitter dispute with her old record company.

Swift won the top award, artist of the year, and four others. She was also given an honorary artist of the decade award, taking her total to 29 American Music Awards, organizers said. That easily outstripped the 24 awards Jackson picked up.

"All that matters to me is the memories that I have had with you guys, with you, the fans, over the years," Swift, 29, told the audience at the ceremony in Los Angeles after performing a medley of her old hits.

Swift had been expected to speak out about a long feud with record industry executive Scooter Braun, who owns the master recordings to her first six albums after Swift signed with a new label in 2018.

Swift accused Braun last week of refusing permission for her to sing songs from her back catalog at the awards show. The public spat culminated last week with Braun's saying his family had received numerous death threats after Swift urged her 122 million Instagram fans to let Braun "know how you feel about this."

But on Sunday, Swift made no mention of the dispute, although she opened her performance wearing a white shirt printed with the titles of her old albums.

"This year for me has been a lot. It's been a lot of good. It's been a lot of really complicated," she said without elaborating. She beat Drake, Ariana Grande, Halsey and Post Malone as artist of the year.

Newcomer Billie Eilish, 17, took home two statuettes for best new artist and best alternative rock artist after a breakout year that saw her top the U.S. charts with her single "Bad Girl."

"You made it all happen," said Eilish, thanking her fans.

Eilish showed her support for environmental causes by wearing a T-shirt with the slogan "No Music on a Dead Planet" as she gave her first awards show performance with "All the Good Girls Go to Hell."

Selena Gomez kicked off the ceremony in her first live TV performance in two years after she underwent a kidney transplant in 2017 and battled anxiety and depression.

R&B singer Lizzo performed her new single, "Jerome," and Camila Cabello and her boyfriend, Shawn Mendes, sang their hit pop single "Senorita," which won the award for collaboration of the year.

British rocker Ozzy Osbourne, 70, who has been sidelined by serious health problems for a year, was mostly seated as he took to the stage with rappers Post Malone and Travis Scott and rocker WATT for their single "Take What You Want."

Punk rockers Green Day got the audience to their feet as they marked the 25th anniversary of their 1994 breakout album, "Dookie."

Other performers included the Jonas Brothers, Kesha, Halsey, Christina Aguilera and Shania Twain.
