I NEED YOUR HELP! (Patreon)

Not to Be OverDramatic BUT!!!!
I need Help with Picking the First Album of Each Artist to listen to on here!
The problem I am running into is, Does the Demo Count? unreleased albums?
I am wanting to start from the beginning and I dont want to pretend like I know where that is so Please, Drop it in the Comments Below... First Full "Album" of

BTS
Dimash
Band-Maid
One Ok Rock
BabyMetal
McFly

We're Starting off with An Album for Each band, then the first concert, then a documentary for the concert if they have it, and so on! But where to begin is the biggest question!

I Plan to have All these album reactions recorded before I go to Hong Kong if possible!
