Concept
According to Cube Entertainment, the concept of Press Play is “a idea of the "play" button on a cassette tape player and the meaning of the title is derived from the indication that "BtoB play time is about to begin"”.
Composition
The EP consists of six new tracks. The first track of the EP, "Press Play", was written and composed by Seo Yong-bae, Seo Jae-woo and by the singer G.NA, who also features on the song.

The second track, "Wow", also first title track of the EP, was written and composed by Kim Do-hyun, Seo Yong-bae and Seo Jae-woo. The song is described to be of "new jack swing" style, which was popular during the '90s, and incorporates the solid vocal and rap skills of the members. The third track, "Lover Boy", chosen as the follow-up track of promotions, was also written and composed by Kim Do-hyun, Seo Yong-bae and Seo Jae-woo. The song is described to also have the '90's retro sound embedded in the track. The fourth track, "U & I", was written by Hwang Sung-jin and composed by Lee Joo-hyung and Lim Sang-hyuk. It is described to demonstrate a sentimental, yet innocent teen-age love story. The fifth track, "Stand Up", was written by Gum and composed by Choi Yong-chan. It is described to inspire and give strength to all listeners who are looking forward to a better tomorrow. The sixth and last track of the EP, "My Girl", was written and composed by Triple A.
