This shows two things: (1) How great a singer Jessica was from the very beginning and (2) how much Tiffany has improved as a singer over the years. I really can't wait to hear what Jessica has in store as a solo artist and I will be preordering her album without hesitation (when she finally gets around to releasing it).

Jessica killed everyone here. I´m so in love with her voice.

I got into SNSD quite late, like 2019. I used to think Tiffany was a better vocalist than Jessica. Maybe she is now because she is still singing a lot, and Jessica has taken a longer hiatus. However, I now see why Jessica was the second main vocalist and Tiffany was lead. Jessica was incredible here. She deserved that title.

Not usually a fan of Jessica's voice but her vibrato is stunning here. I wish I was as good as her;; the group won't be the same without her

Jessica so owned Tiffany here lmao she was literally shining. Jessica has amazing control damn. She has more control in her voice than my life lmao.

Jessica's voice is so angelic.

Undoubtedly, Jessica is gifted at singing. Her voice is the easiest one to recognize. And she will never let us down, her solo album "With love, J" was so good.

During their debut Jessica carries most of the High notes in all of their songs.

Even though tiffany is my bias in snsd. This song really suits with Jessica and Taeyeon. tbh.

Jessica (Jung Soo-yeon) and Tiffany (Hwang Mi-young) were both born in San Francisco U.S.A.

Jessica's voice is perfect in this song.....
