So, I've been listening to Somi's new song What You Waiting For for the past 1.5 hours and I gotta say:
It sounds dated.
I really liked the beginning, however the chorus was underwhelming. It sounds like early 2010s Western Pop. There was nothing unique. It feels kinda like a B-side to me. For her first comeback - especially after more than a year of waiting - I expected something more. There was no change, I waited for something in the chorus and the 2nd verse caught me off guard. (I appreciate the sung chorus tho) I also felt like she didn't have the chance to let her vocals shine. The MV is really nice, however the song is in my opinion not title track worthy.
Now onto Birthday:
I didn't like it either on the first listen, however it grew on me after the 2nd or 3rd one. The beat was fresh and the chorus really nice, it showcased her vocal ability. Nowadays, I don't listen to this song that much anymore, because the "oops, you're not invited" became annoying with time, however I still prefer it over WYWF.
