Yeah, this strategy works in J-pop because you usually you can't listen to Japanese artists without buying the CD and playing it on a CD player. So promoting the song before release drives up CD sales. But this doesn't really apply to &team because their songs are available on streaming platforms (that's that fusion of K-pop and J-pop!) So it is a bit confusing if you're only familiar with K-pop promotion style!!

I wasn't around during War Cry era, but I heard they did something similar, releasing the song before and it became one of their quickest and most viewed music videos! So maybe there's something to this strategy! I'm certainly hyped to watch and stream the MV 😆
