The Mnet Asian Music Awards, K-pop’s biggest annual awards night, was broadcast live from South Korea on Sunday night. BTS won big, as expected, Twice surprised with a performance of new song and veteran singer BoA celebrated her 20th anniversary with younger artists covering her hits. Here are five things you need to know about the 2020 Mama awards . Twice debut new song South Korean award shows usually emphasise remixes and it’s rare for premieres to take place. But during Sunday night’s ceremony, Twice surprised with the debut performance of their previously unreleased song Cry For Me after performing their other recent singles. Twice’s fans, known as Once, were very excited, and Twice trended across many global social media platforms and the news topped various portal sites in South Korea. The song was co-written by Ryan Tedder of One Republic, who posted on social media that it would be Twice’s next single on social media, but the release date is not known yet. Collaborations galore Whether it was girl groups covering BoA’s songs, including Aespa’s Winter making a surprise appearance, or Jessi and Hwasa covering Rain’s viral hit Gang , Monsta X and rookie label mates Cravity teaming up, Tomorrow X Together covering BTS’ Dynamite , or Stray Kids, The Boyz and Ateez going at it in regal, warlike performances, collaboration stages made the six-hour 2020 Mama awards worthwhile. BTS the big winners BTS took home all of the grand prizes across four categories, known as daesang awards in Korea, being recognised in the song, artist, album, and worldwide icon of the year categories for their various achievements of the historic 2020. Collectively, BTS received eight awards, while Suga, who is recovering from a shoulder injury but made an appearance over the phone to give an acceptance speech and as a hologram during a performance, also won one in collaboration with IU for their song Eight . After winning the artist of the year award, J-Hope said: “Big thanks to Army, who is watching at this time. I am truly grateful that we are able to come here each year and perform for you. A lot of things have changed this year, but my gratitude remains constant. “Every step BTS takes, every growth along the way – we hear about how great our fans are. I want to stress that our Army is the reason we are able to make this acceptance speech and perform on stage. I don’t say this enough, but I would like to take a moment to thank the rest of the band. Because of you, I was not lonely or sad – we all did good this year, I love you! Especially Suga, get well soon – wish you were here. This award is not complete without you.” Big three are back All of South Korea’s historic big three K-pop companies were in attendance for the first time since 2015. JYP, SM, and YG Entertainment were all represented after years of industry fallouts resulting in the latter pair not sending artists to the Mnet Awards for several years. YG Entertainment artists haven’t been in attendance at Mama shows since 2016, even though they had been front-and-centre since Mama began in 2009, but this year the company’s rookie group Treasure had their own set and won several awards. The event also saw the return of several SM Entertainment acts after last year only saw WayV appear, and no SM artists perform in 2018. This year, however, saw NCT and its various teams, including WayV, as well as BoA, who performed second to last and had numerous songs covered by other acts in celebration of her 20th anniversary as an artist, in attendance. Unwanted guest The coronavirus took centre stage at 2020 Mama. Not only were there frequent mentions of the virus throughout the night, but many award recipients gave their acceptance speeches while wearing masks, or briefly removing them to speak. Additionally, in between each performance and award announcement, a woman in a silver bodysuit was seen cleaning microphones with disinfectant.
