Recent IVE title tracks doesn't have that IT factor their previous songs had imo

I don't understand why, but I don't really like their title tracks after I AM. On paper, they seem really good, but I just don't feel like listening to them again and they are kinda meh. I admit their bsides are still very good tho.

Did they have a change in producers or management? Do you think its because they are trying to change their sound, but it just doesn't stick?
