Puzzle number 2001 of BTS’ Armypedia is also the first piece in the Spotify x BTS collaboration. The QR code has the date December 4, 2018 and it leads to Jin’s 26th birthday.

On that day, the oldest member of the septet South Korean boy group wrote a hand-written note for the Army (fandom name). In his letter, he said that he’s happy not only because it’s his birthday but also because he has his fans.

The second clue released today is for the May 17, 2018 entry when BTS did their interview with Access. You may follow all the clues released in Spotify through the Twitter account @SpotifyKdaebak.

This is the first puzzle piece for SpotifyxBTS.
