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.
