Like literally everyone else, BTS' 2020 plans were completely derailed by COVID-19. Instead of touring the world, they found themselves stuck at home, and so they turned to doing what they do best: creating music.
In August 2020, they released their very first all-English single, "Dynamite", saying they wanted the song to give energy and joy to fans around the world going through a hard time. They also released several remixes of the track, and "Dynamite" earned BTS their first Billboard Hot 100 number one and a Grammy nomination.
In November 2020, BTS released a new album BE, which features "Dynamite" and six new songs, including title track "Life Goes On", which also hit number one on the Billboard Hot 100. The album reflects their experiences during the pandemic, with a particular focus on mental health, their relationship to their work, and their yearning to see fans.
While all seven BTS members have always participated in creating their music to some degree, BE saw them take on a greater level of involvement than ever before. In addition to more input in the songwriting process, different members each took the lead on various aspects of the album creation, such as the concept photos, packaging, and music video. They documented some of this work in a series of livestreams in the lead up to the album release.
BTS has not yet announced what their next era will be, although they do have a Japanese compilation album coming out in June called BTS, the Best. It features new single "Film Out".
