I started playing a bit today again and I thought we could also get money by posting videos like yt. It can be named differently like idoltube or whatever the point is to be like yt where you get likes, dislikes and you have to get the amount of subscribers (idk like 20k) to start earning money from videos.
You could post MV's, or just videos like dance covers of other famous groups or singing covers. Or you could just post vlogs. It would nice to see dislikes for example if people dislike some girl. Or even hate comments for the company if you haven't released any new music for a while.
For MV you could post a professional MV that costs a lot but also very low budget and then people could complain and dislike it. Also if they do a sexy cover/concept people can hate and complain. Or they can actually like it and it goes viral.
Maybe if you could post a statement on social media like "if we don't do well next comeback we have to disband or let go some members" just to make people pity buy the single/album or if people would pity stream our videos (and we could earn more from MV views) also we should get money from MV's weekly not just once. Once you get more views you still get money. So it's not a one time payment like singles where you only get the amount on release day.
And singles should probably be bought later like when group gets more fans new fans could buy older singles.
Just a thought. That would be more interesting than just clicking on "promotion" because we'd actually see feedback (views, likes, dislikes, comments)
