Where do you find informations about groups?
As much as possible I am looking at every groups OFFICIAL SNS Accounts. Yes chingu! (E.g Facebook, Twitter & Official Website) I used wikipedia back then but I stop since everyone can edit informations there.
Why other videos don't have marks from companies? Are those videos official?
If a company don't own youtube channel they post it in music channels like 1TheK, CJE&M, Genie, Bugs Official and more. Some cases companies post it in their yt channel and posted it also in music channels. Others don't put marks like SM & JYP do. Same same they are all counted in charts you can view it both but I'll just put the company video one.
why i can't save image from this site?
Magic :)
