Exid- up n down
Momoland- bboom bboom
Brave girls- rollin
All these songs went viral but comparing their Youtube views- Bbboom bboom has 500 million views which is huge; Up n down has 100 million views while Rollin has 5 million views. What do you think is the reason for huge difference between their views? is bboom bboom more catchy than others? Or many international kpoppers are still unaware that Rollin went viral. Personally i like up n down the best out of them.
