Swift wins top Grammy; Kendrick Lamar wins 5

LOS ANGELES -- Taylor Swift's official switch from country to pop with her multi-hit, best-selling "1989" album brought the singer her second Grammy Award win for album of the year.

Swift was shocked when she won the night's top prize, beating out Kendrick Lamar, Chris Stapleton, Alabama Shakes and the Weeknd. Swift used her speech to encourage young women who feel defeated at times or discouraged by others.

"There are going to people out there that try to undercut your success or take credit for your fame. ... You don't let those people sidetrack (you)," she said.

Swift won Grammy album of the year for "Fearless" in 2009. She won three awards Monday, including best pop vocal album and best music video for "Bad Blood," at the Staples Center in Los Angeles.

Alabama Shakes also won three awards, though Lamar was the night's big winner with five.

He won best rap album for "To Pimp a Butterfly" as well as rap performance, rap song, rap/sung performance and music video. Along with his wins, Lamar also had a show-stopping moment when he took the stage.

He started as he appeared beaten, in handcuffs, with chains around his hands and a bruise on his eyes. He went on to fuse rap, jazz, reggae and African sounds for a commanding performance as he rapped "The Blacker the Berry" and the Grammy-nominated "Alright" passionately. He ended with a map of Africa, and the city of Compton imprinted in it.

"Hip-hop, Ice Cube, this for hip-hop, this for Snoop Dogg ... this for Nas. We will live forever, believe that," said Lamar onstage when he won best rap album.

Mark Ronson and Bruno Mars won two awards for "Uptown Funk," including record of the year. Ronson gave a shout-out to Prince, James Brown and George Clinton for being leaders in funk.

"This is dedicated to the fans right here," Mars said.

Mars introduced Adele, who sang "All I Ask," which they wrote together for her new album "25." She was accompanied by a piano behind her, but the audio sounded off and appeared to throw off her performance.

"There was a brief 5- to 8-second technical issue that was out of our control," a CBS spokesperson said.

Justin Bieber started "Love Yourself" on guitar in good form, but ended with a vocal struggle.

Little Big Town and Demi Lovato, however, had shining moments during their performances, hitting impressive and smooth high notes.

But Bieber had a shining moment: He won his first Grammy on Monday night for best dance recording for "Where Are U Now" with Skrillex and Diplo.

The Grammys also marked first-time wins for Alabama Shakes, the Weeknd, Stapleton, Pitbull and Ed Sheeran, who won song of the year for "Thinking out Loud."

"We wrote it on a couch in my house," he said of his hit song he wrote with Amy Wadge, which also won him best pop solo performance.

Alabama Shakes' three wins included best alternative music album for "Sound & Color," as well as rock song and rock performance for "Don't Wanna Fight," which they performed.

The Weeknd, who won two awards, performed in a cube brightly lit for "Can't Feel My Face" until he switched to a piano-tinged version of his upbeat hit "In the Night."

Stapleton won best country album for "Traveller."
