Positions In A Group

Hey guys~
So I bet some of you are still confused with positions in a group, that's why I'm here to explain it.

Main: Person who does the most and who is the best at doing it.
Example: Main vocalist is someone who sings the most, sings the catchiest part and is the best at singing

Examples of main vocalists:
100%-Rokhyun
B.A.P-Daehyun, although TS claims both Daehyun and Youngjae are lead vocalists
B1A4-Sandeul
Beast-Yoseob
Block B-Taeil
BTOB-Eunkwang
C Clown-Kangjun
CN Blue-Yonghwa
Infinite-Sunggyu and Woohyun. Woollim claimed so and I also can't pick who is better at singing and sings more than another.
MBLAQ-G.O
Shinhwa-Hyesung
Teen Top-Niel
VIXX-Ken and Leo. Jellyfish claimed so and yes, I don't know who is better and has more parts. I think Ken is the main though, but I'm not sure.

Lead: Person who does well but not better than the main and gets quite a lot of parts but not as much as the main

Example: Lead rapper is someone who raps better than the others but not better than the main rapper

Examples of lead rappers:
100%-Changbum
B.A.P-Yongguk
B1A4-CNU
Beast-Doojoon
Block B-P.O
BTOB-Minhyuk
C Clown- I don't know but I think it's T.K
CN Blue-No one raps except Yonghwa (and he doesn't even rap that often) so no one is the lead rapper
Infinite-Hoya
MBLAQ-Thunder/Cheondoong
Shinhwa-Andy and Junjin. Their raps are both not better than Eric's
Teen Top-C.A.P
VIXX-Hongbin as what it says in their official website, but I consider him as visual instead

Visual:Person who is good looking and does singing/rapping/dancing well although not as well as the main ones.

Examples of visuals:
100%-Minwoo
B.A.P- Although they actually don't have one, I consider it as Himchan because he raps kinda well
B1A4-Jinyoung
Beast-Gikwang
Block B-Actually, no one lol. But I'll say it's Jaehyo
BTOB-I da naaaahhh
C Clown-I don't know. Like every single C Clown members are good looking in my perspective
CN Blue-Yonghwa. Again.
Infinite-L/Myungsoo
MBLAQ-I don't think they have one
Shinhwa- Minwoo? I don't know lol
Teen Top-Chunji
VIXX-Hongbin

Face Of The Group: Is someone who is the center of the group and who is placed because of his/her face. In other way, they're just spamming if they don't have the good looks, but these days faces of groups usually spams at first but then they try to improve so they are not spamming.

Faces of groups examples:
100%-Sanghoon
B.A.P-I always think that Jongup is but he's great at dancing so I guess I can't say that he is one
B1A4-Gongchan
Beast-No one. At first I thought it's Dongwoon but then I realize he doesn't have that much fans
Block B-Jaehyo. But he can sing so I don't know.
BTOB-Peniel. But he is one failed example of face of the group.
C Clown-No one. Maybe Siwoo if I need to mention one.
CN Blue-No one. Everyone has their own parts.
Infinite-No one.They have a visual instead.
MBLAQ-Cheondoong
Shinhwa-No one
Teen Top-Because Changjo is not that appealing in the early clap mad man era, so I'll say no one.
VIXX-No one

Sub Vocal: Is someone who sings the baking vocal/vocal without notes part (not rap). Doesn't need to have really good vocals. Usually faces of groups gets this part.

100%-Sanghoon
B.A.P-Himchan and Jongup
B1A4-Gongchan
Beast-No one from my view, but maybe Doojoon?
Block B-No one
BTOB-No one. You maybe will say it's Minhyuk because of the 2nd confession narration thing but BTOB's other songs don't have that kind of part
C Clown-No one
CN Blue-Minhyuk and Jungshin
Infinite-Sungyeol
MBLAQ-No one
Shinhwa-No one
Teen Top-No one
VIXX-Hyuk

So, do you understand now? If you don't, then it's not my fault. Bye~!
