That chorus is absolute fire.
It needs time to determine if it surpasses Wannabe and Dalla Dalla but it IS one of their best choruses for sure (not as much the getting loco but the sung chorus!!). The rest is good, it'll have to grow on me a bit but on the second listening (first on Spotify), it already does.
It's up to taste but while I think Icy and Not Shy were okay, Mafia less so, Itzy's sung choruses are the best
Now on to the album!!
