Display Morerm does these vlives after each album drops, where he talks about each and every song on the album, what went on during the process of making the song, shares his version of the song that got rejected hehe
its gives a good insight on his involvement and other member's involvement in the album making process

The fact that only you (or if I missed out anyone before please forgive me) mentioned RM kinda make me think man is super underrated.
RM of BTS involved in almost 90% of BTS dischoreographies. Writing, produce, arrange the music + album concept and part of the recording engineer too. He doesn't just write lyrics for the raps, in fact from the beginning till the end for almost all BTS songs. I would say RM & Suga both are the backbone, with Jhope next. RM literally responsible for everything. Members did say RM will be the start and end for BTS songs, I mean it is to the points that he has not have a time for his own mixtape + producing to others. While the members are chiling, he ain't got time for that. This is where Jhope will be in the picture supporting RM. As for Suga, he has more chance to produce outside BTS since RM + Jhope are there for BTS. Believe that's what he enjoyed the most. I mean look at the KOMCA and see yourself where are these 3 in the lists.
It's only a matter of time before RM will top of the list since he's the youngest in top 5 KOMCA
