Germany's Kraftwerk was also among the night's winners.At the gala awards ceremony on Sunday evening in New York, the 32-year-old musician triumphed with his album "24K Magic," edging out rapper Jay-Z and Kendrick Lamar. His song "That's What I Like" also won top honors. Altogether, Mars took home six of the music world's most coveted awards. German electronic music pioneers Kraftwerk took this year's top honors in the category of best dance/electronic album for "3-D The Catalogue," while Canadian singer Alessia Cara was named best new artist. English pop songwriter Ed Sheeran took top honors for best pop solo performance for "Shape of You." Sheeran, a multiple winner at the 2016 Grammys, was the most streamed artist on Spotify in 2017. But "Despacito" by Luis Fonsi and Daddy Yankee, the most widely viewed video ever at 5 billion views, was edged out in the song and record of the year categories. In "music's biggest night," women wore white roses in solidarity with the #MeToo movement, while black and Latino musicians dominated in the top four categories.

Politics dominate the night The performances had a distinctly political ntone this year, highlighting everything from Donald Trump's presidency to sexual harassment and gun violence. Against a backdrop of American flags and flanked by dancers in camouflage fatigues, Lamar was joined by U2 frontman Bono and comedian Dave Chappelle in the song "XXX." The lyrics include the phrase, "America, God bless you if it's good to you." At the end, Lamar stood among men dressed in red hoodies and seemingly gunned them down one by one. Lady Gaga immediately followed with her songs "Joanne" and "Million Reasons." Clad in white feathers that also draped over her piano, she evoked a bird or an angel. At the end, she whispered, "Time's up," in another reference to the #MeToo movement. Echoing her, Reba McEntire, winner for best roots gospel album, said, "My message on this is for everybody to treat each other like we want to be treated." In tribute to victims killed at live music events in Las Vegas and Manchester in 2017, Maren Morris, Eric Church and the Brothers Osborne performed a quiet version of Eric Clapton's "Tears in Heaven," with the names of victims displayed on panels behind them. The musicians had performed at a country music festival in Las Vegas in October, site of the worst mass shooting in modern US history. Posthumous Grammys The late "Star Wars" actress Carrie Fisher was honored posthumously for "The Princess Diarist." In her audio book, she related her memories of the filming of the first part of the sci-fi saga. Fisher died of a heart attack in December 2016. Canadian singer, songwriter and poet Leonard Cohen, who died in November 2016 at the age of 82, was also honored. "You Want It Darker," the title song from his last studio album, won for best rock performance. Grammy performers Gary Clark Jr. and Jon Batiste also paid tribute to music greats who died in 2017: Fats Domino and Chuck Berry.
