Whatta Man (Good man)I.O.I

This is the debut single of I.O.I, the now-legendary idol group that emerged from PRODUCE 101.

The song is about seducing a charming man, and while it keeps I.O.I’s energetic and lively image, it leaves a strong impression of being sexy and powerful.

Every member is great at dancing and looks so cool!

"When the Cherry Blossoms Fall (When The Cherry Blossoms Fade / 桜が散ったら)" by I.O.I

I.O.I, a group formed by members selected on the Korean audition program PRODUCE 101.

Their song When The Cherry Blossoms Fade, included on the mini-album Chrysalis released in 2016, portrays the bittersweet feelings that come with the end of spring.

It beautifully expresses the anxiety of love that grows as the seasons change while spending each day with someone you love.

It’s K-pop whose choral arrangements unfold over a somewhat wistful melody that evokes the season when cherry blossoms fall.
