1. Dream Girls
"Dream Girls" was intended to be reminiscent of Girls' Generation's "Into The New World". It has a classic sports-themed/school girl music video that most girl groups do at least once. The best part of I.O.I's debut song is the lyrics. Rather than a sappy love song (which is nice, but overdone) the message is to confidently chase your dreams and never quit.
I.O.I. debuted their first sub-unit of eight members with a remake of the 1963 track "What A Man" by Linda Lyndell. It is the edgiest the group has ever been and the song is a platform for their strong vocals! Chung-ha, the main dancer, made the choreography for the song and the music video features leather and a lot of sass.
JYP of JYP Entertainment collaborated with I.O.I for this track. It's playful, with a very fast rhythm and childish charm. The lyrics describe a girl trying to tell if a boy really likes her and how to cautiously approach a relationship. This is I.O.I last release before their disbandment and they really go out with a bang. Due to the over-repetitive chorus, you won't forget this song for a while!
