Musically, "Free Free" is the creation of a newly founded genre by Nakata titled Eropop, which he generated by combining 1980s pop, house and disco music; furthermore, the single also incorporates influences of contemporary EDM. The lyrical content is based on the theme of freedom and having fun. With that said, erotica is another factor that inspired the tracks lyrics and Suzuki's image for the track. Backed by synthesizers and keyboards, it is Suzuki's first English language recording and her vocals are processed through pro-tools such as autotune and vocoder.
