Taemin talked about his first solo album, saying, "'Press It' is a full album with 10 songs that I participated a lot in myself, and I also worked on collecting the songs. As a result, the album shows a lot of my color."
Oh his title song, he said, "'Press My Number' is an urban pop dance song worked on by Bruno Mars and the producing team The Stereotypes. The choreography was changed multiple times and I practiced a lot to have good chemistry with the dancers."
He also chose Kai as one of the artists he wanted to work with, saying, "I want to work with my friends. I think if I work with friends who I've been close to since we were trainees, I could have an energetic outcome."
