BTS — Proof Tracklist for CD 2

BTS Proof Tracklist — CD 2

Looks like CD 2 includes only solo and subunit songs, but randomly ends with "Dimple"! I can't wait to hear "Run BTS," which is also co-written by Jungkook and Daniel Caesar, who they've never worked with before. Is it OT7? Is it a subunit? Maybe they're opening and ending this CD with OT7 songs? I also find it interesting that they chose to include "Cypher 3" instead of "Cypher 4" given that the rest of the tracklist includes songs from Love Yourself or later, but chose to exclude "UGH!" altogether, which is the most recent rapline song. What will CD 3 bring???
