Compton Logan Cooke Camo Jersey , California rapper Lamar went into the awards with 11 nominations, and had looked on course to take album of the year for his critically-acclaimed To Pimp a Butterfly, but it was country-turned-pop artist Swift who won with 1989, the best-selling album of 2014.
Swift, 26, made history as the first woman to win album of the year twice after also taking the Grammy in 2009 for Fearless Ronnie Harrison Camo Jersey , and delivered a feisty acceptance speech on female empowerment.
"To all the women out there ... there will be people who try to undercut your success or take credit for your accomplishments or your fame," the singer said on stage, adding: "Don't let people sidetrack you."
The speech appeared to be a swipe at Kanye West who last week released a song called "Famous" in which he claimed that he made Swift famous after the 2009 MTV Video Music Awards incident in which West hijacked Swift's win live on stage.
R&B singer Bruno Mars and producer Mark Ronson won record of the year for their upbeat track "Uptown Funk!"
"We wouldn't be up here if it wasn't for the people dancing to this song," Mars said.
British singer-songwriter Ed Sheeran won his first Grammys, including song of the year for "Thinking Out Loud," receiving a big hug from Swift as he went up on stage.
Pop star Meghan Trainor Telvin Smith Camo Jersey , who broke out last year with her body-confident hit "All About That Bass," was named Best New Artist, tearfully thanking music executive L.A. Reid "for looking at me as an artist instead of just a song-writer."
