"Hello" combines 808 and bass guitar, while "Girls Girls Girls" is a hip hop and electropop song written, composed, and produced by J.Y. Park; it contains a sample of the exclamation "eomona" (어머나) from Wonder Girls' "Tell Me".[3] The lyrics are cocky and the chorus features lines such as "Even when I shake my body a little, even when I don't do anything, girls, girls, girls they love me."[2] "I Like You" fuses elements of R&B and hip hop with an electronic sitar and a Bollywood-inspired beat.[2][3] "Follow Me" is based on southern hip hop and "Like Oh" blends urban club and EDM.[3] The album closes with "Playground", an R&B piece that expresses the excitement and joy of finding a new love, compared to the dreams and memories of childhood.[3][4] The theme of the song is not love, but "me".[5]
