BTS have 'Merry Go Round' out. The official music video went up on BANGTANTV, the group's own channel, on September 26 at 12:00 AM KST and runs four minutes and 19 seconds.

At the time of writing it carries 7,735,661 views, 742,632 likes and 32,447 comments. Those are readings taken at one moment rather than running totals, and the page itself keeps the live figures for anyone who wants to check them.

The description is mostly official links and hashtags. There is no album release date in it, no credit list and no tracklist, so the post settles the song and the day it landed and leaves the rest open.

One hashtag is worth a second look. Alongside the group and the song, the description tags ARIRANG, and separate uploads on the same channel carry titles naming a BTS world tour by that name. The shared name is what the tag establishes, and nothing further than that.
