Background and development
After performing at the Nippon Budokan in 2011, F.T. Island recorded the song "Let It Go!" in commemoration of the event. Recorded during the same period, "Neverland" was composed by Choi Jong Hoon. Described as an energetic song, he recorded the guitar as the final bit to make the instrument the most prominent in the recording. He penned the song "Stay", which is based on his personal relationship experiences. He initially wrote the lyrics in Korean, then translated them into Japanese, using a translator where he was unable to translate the lyrics by himself. The process between three and four hours.

Choi Min Hwan and Song Seung Hyun worked on the songs "Always" and "Compass" together while in high school. Discussing "Always", Choi Min Hwan compared the song to "Satisfaction" in that one may feel a similar "atmosphere and a strength", but noted that there was more emphasis of sorrow in "Always". "Paper Plane" is a medium-tempo song, which features a dense snare drum. "Distance" was written by Kenn Kato, Song Seung Hyun and Lee Jae Jin, and composed by Corin. Lead singer Lee Hongki had difficulty singing the song, stating that the key he sang in was very high.

20 [Twenty] was recorded while F.T. Island was in the midst of promoting in South Korea, which limited their time on the project. Determined to convey the proper emotions of the songs, they "made sure to stop and interpret every part of the lyrics". F.T. Island aimed to make 20 [Twenty] their most mature album to date. The title of the album refers to the average age of the band members.
