GD x Taeyang's song is super cool and I'm sure I'll be bopping away in the car, however they overused that beat drop. It was surprising the first time, but I feel it would have had more power if it was more isolated (used like twice instead of however many times it was used).
The beat drop itself though was very Diplo/Major Lazer and that deserves some praise.

Oh and Taeyang's pre-chorus/buildup is my favourite part.
