The first time for any of the members to try rapping
Seohyun: I think Hyoyeon unnie did the best job at rapping.
Tiffany: Hyoyeon loved music with a strong beat and groove ever since she was a trainee
so she thought the song was awesome when she first heard it.
Hyoyeon: I thought it was a little hard when I was recording, but when I heard the finished product, I was pretty satisfied. (laughs)
