It's finally here! Let's get to it. Listen and watch the music video, the stage performance (this one's got good fan chants), or the dance practice. Onward to notes:

• GLAM's biggest hit, In Front of the Mirror, a "trot, Europop and hip-hop" song. They disbanded in 2015 after a blackmailing scandal.
• TIME interviews Bang Si-Hyuk.
• Here's a fan-made explainer for the BTS Universe. But to give you a taster, the BTS Universe includes:
• (includes gore, themes of abuse, suicide, homicide)
• music videos,
• extended releases of the same music video,
• Japanese music videos, but only the little symbolic teasers outside of the heavy choreo focus,
• prologue teasers, released right at the top of the promo cycle,
• epilogue videos released at the tail end of the promo cycle,
• seven short films,
• the next single's music video,
• booklets that came with the albums (and note the translation effort of the fans!)
• BTS Universe social media posts,
• a sixteen-episode web cartoon,
• a blog for a fictional flower shop that kept getting rewritten, since it's a time-travel story,
• sentence teasers in poster releases, other scattered social media accounts, other snippets of music videos of dubious canonicity... the list continues.
• By way of comparison, watch EXO's MAMA, and then their second release, Wolf (CHOGIWAAAA 🐺)
• TXT, BigHit's newest boy group, also has an extended universe associated with it - the TU, or +U.
