The World On arirang

This is the title track of AOA's fifth mini album. It's a retro-style song influenced by modern funky pop style that has a catchy hook. The whistling sound and refreshing guitar melody that echo across the powerful beat go perfectly with the summer, which is a great season to party.

This is Yellow Bee's debut song that describes the experience of having a crush on someone. The upbeat rhythm and melody and the candid and lovely lyrics stand out. It describes the nervousness you feel around your crush with a "hiccup."
