I loved the song, Zimzalabim disappointed me so much so it was nice hearing a song that I actually like, their previous comeback is probably on my "worst kpop songs ever list" and this one is probably in my top 50 list.
definitely liked it more than their recent comebacks. tbh i haven't liked any of their title tracks from bad boy to zimzalabim, so i found umpah umpah to be a refreshing change, although in the grander scheme of rv's discography it's definitely not one of my favorites. its solidly nice. reminds me of the kind of summery boppy song you'd hear in an early 2000s summer chick flick where a city girl goes to spend the summer at a beach town and develops a romance with some surfer dude who works at the boardwalk eatery and initially dislikes her bc she's from the city. lol
