Step aside winners. The Grammy Awards have long belonged to performers and unexpected moments - and Sunday's show was no different with Kanye West rushing the stage, Pharrell Williams' orchestral bash and a poignant plea to end domestic violence.
Grammys take stand against domestic violence
Amid the music and celebration, the Grammys turned serious for a moment when President Barack Obama called on musicians and music fans alike to pledge to stop domestic violence.
"It's not OK and it has to stop," Obama said in a spot aired during Sunday's Grammy Awards. "Artists have a unique power to change minds and attitudes and get us thinking and talking about what matters."
Domestic violence survivor Brooke Axtell followed, taking the Grammy stage to share her experience as a survivor and to urge others to recognize their worth and seek help to save themselves. Her life was saved, she said, when she sought help at a domestic violence shelter.
Katy Perry followed with a solemn performance of By the Grace of God.
Fifty shades of Madonna
In the night when the music industry crowned British soul singer Sam Smith with a leading four Grammys, including song and record of the year, viewers at home were treated early on to Madonna's burlesque homage to bullfighting.
Pop music's 56-year-old grand dame of scandalizing spectacle, performed her new song Living for Love in red and black lingerie with 20 dancers wearing bulls' horns and rhinestone-covered faces twirling the singer about. She was later joined by a choir of more than two dozen singers.
Paul McCartney - who later performed FourFiveSeconds with West and Rihanna - gave the audience a light moment on a mostly somber night by dancing alone in the audience to ELO's Jeff Lynne playing the 1975 hit Evil Woman.
With the camera up close, the former Beatle stopped, looked around and sat down with a sheepish smile, drawing laughter and sending "Sir Paul" trending on Twitter.
Taylor Swift's ex takes dig at her on TV show
Singer Taylor Swift's former boyfriend John Mayer has jokingly said he is prepared to be avoided by her at the upcoming Grammy Awards.
The 37-year-old Your Body Is a Wonderland hitmaker made the cheeky comment about the Blank Space singer while hosting the Late Late Show on Friday night, reported Ace Showbiz.
"You can see me at the Grammys doing what I do best, being avoided by Taylor Swift. That won't make the internet at all," he joked. The audience responded with laugh.
Mayer and Swift, 25, briefly dated in 2009. While Swift will be presenting a the Best New Artist award, Mayer will perform at the 57th Grammys.
Pop giants Pharrell Williams and Beyonce win early Grammys
The music industry's biggest night kicked off with some of the top names in pop music -- including Madonna, Paul McCartney, Rihanna and Kanye West -- slated to perform to a global audience from Los Angeles.
Among dozens of awards announced in a smaller ceremony beforehand, Williams won for Best Urban Contemporary Album and for Best Video for Happy, his viral ode to happiness that spawned hundreds of imitations around the world.
Williams, 41, has emerged as a star in his own right with Happy after years on the sidelines as a producer.
Last year, he enjoyed Grammy nominations for his work both on Robin Thicke's lustful Blurred Lines and with the French electronic duo Daft Punk, who were 2014's big winners.
"Life is a carousel," Williams said as he walked the red carpet at the Staples Center in Los Angeles in a gray Adidas shorts suit.
Sam Smith plans to eat like a winner
How will Sam Smith celebrate after the Grammys?
He wants to go to In-N-Out, that overwhelmingly popular Southern California burger chain. And don't worry about all those calories he'll rack up with a double-double or two. Smith says he's been dieting just for this night.
He was nominated for six Grammys, including for record, album and song of the year, something he called "surreal." But not as surreal as when Stevie Wonder asked him to drop by his dressing room. Wonder ended up performing one of Smith's songs.
"That's just crazy," he said on the red carpet.
Win or lose, drunk or sober, Hozier will be busy
Whatever happens to Grammy nominee and performer Hozier, he has a music video to shoot after he's finished with the Grammy Awards.
"Hangover or not, there will be a music video," the nominee for song of the year said on Sunday's red carpet.
Lang Lang keeps mum ahead of Grammy show
Will the third time be the charm for Lang Lang?
After teaming with Herbie Hancock and Metallica for past Grammy performances, he's back this year for another go.
This time it will be with - well - the Chinese concert pianist isn't saying. But word is it will be with Pharrell.
He did hint that it will be with a popular male singer and feature an arrangement by Hans Zimmer.
"The Grammys are always filled with surprises, whether it's making new friends or the performances," he said before the show.
Tiesto's birthday gift becomes Grammy win
DJ-producer Tiesto remixed a song for his birthday and now he has a Grammy for it.
Tiesto remixed John Legend's pop ballad "All of Me," which won the Grammy for best remixed recording, non-classical. Tiesto said he "made this remix spontaneously" for his birthday. "I gave it away as a free download," he said.
Tiesto said Legend enjoyed the remix so much that made it official. The version was a hit on pop radio in addition to the original version.
Legend's live version of the song is nominated for best pop solo performance. The song peaked at No. 1 on Billboard's Hot 100.
