Their exclusion from the nominations drew the ire of the boy band’s legion of fans—known as the BTS Army—almost immediately on social media.

Fans were flabbergasted the group could be edged out of the awards despite BTS becoming one of the biggest musical sensations worldwide within the last 11 months. The band’s hit album Map of the Soul: Persona marked their third chart-topping record in less than a year. The album outsold even the most popular of American artists, including Beyonce’s Homecoming, which released the same week as BTS’ album.

“Someone tell me how bts, didn’t get any Grammy nominations…like map of the soul persona sold over 4 million copies, A MINI album, had the most views for their music video, hard more impact that a majority of artists this year.. #GRAMMYs,” a fan wrote on Twitter on Wednesday.

While Bon Iver, Lana Del Rey, Billie Eilish, Ariana Grande, H.E.R., Lil Nas X and Vampire Weekend picked up nominations for Album of the Year, BTS was also shunned out of other categories fans felt they belonged in like Best New Artist, Best Pop Duo/Group Performance, Record of the Year and Best World Album.

The Recording Academy’s failure to nominate BTS—or any other K-Pop group—for any awards caused some fans to question the industry’s standards for diversity.

“Lmao if a white artist did 1/10 of what BTS achieved this year they’d get 5 Grammys nominations but ANYWAY !!!’” one Twitter user wrote.

Another called out the Grammys for only supporting diversity within the music industry when it best suits them. “BTS deserves way better, aesthetic diversity isn’t it,” the tweet read.

Other prominent awards shows have created new categories to recognize K-Pop artists—MTV debuted a new Best K-Pop category at the 2019 Video Music Awards, which BTS won—or have included the group in categories with other major pop artists. For the upcoming American Music Awards, the seven-member group is nominated for three awards including Duo or Group for Pop/Rock of the Year, Social Artist of the Year and Tour of the Year.

The lack of diversity at the Grammys is an age-old argument, and the Recording Academy has long been scrutinized for it’s lagging acknowledgment of global musicians and the impact non-white races and cultures have had on the industry.

Back in 2019, the organization attempted to address its lack of diversity by changing how it recruits new voting members. However, the Recording Academy’s efforts only sparked more outrage when the new system introduced more stipulations, requiring potential new members to submit professional recommendations and undergo peer evaluation on a “range of criteria, including craft, genre and overall diversity” on top of the standard application process.

The Academy members’ votes determine who will be included in the official list of nominees each year.
