I'm very confused.
Since my trainee days as a nugu kpop fan I noticed there has been ALWAYS a pattern in the industry: kpop songs are mostly 2 or 3 songs mashed up in order to make ALL the members perform (unlike american acts that are known for having filler members that never sing).
Sure, sometimes it stands out more but at the end of the day it's the same essence. Pretty much always the pre-chorus or bridge or dance break pops up with a weird-experimental beat:
