Background and release
Initially, April was set to make a comeback in March 2020 but on March 11, DSP Media announced that the group would postpone their comeback to April 2020 amid the coronavirus concerns. On April 10, a poster teasing the group's comeback was posted which revealed the mini album's title "Da Capo" and the release date, April 22. According to DSP Media, the album's title "Da Capo" is a musical term which means "from the beginning". On April 11, a story film was released, hinting at a sci-fi themed, a surprisingly darker concept compared to April's previous releases. The mini album's title track was revealed to be "Lalalilala". Subsequently, each member's individual teaser and unit teasers were released from April 12 to 19, with the tracklist being revealed on April 16. A music video teaser was posted on April 21.

Da Capo and the music video for "Lalalilala" were released on April 22.

Composition and reception
"Lalalilala" was written and composed by Kang Myeong-shin & moonc, both of whom had worked with April on their previous release. It is an upbeat, disco-influenced EDM track with a repetitive hook, and gets less intense during the verses than the chorus, with a middle-eight rap from members Chaewon, Rachel, and Yena. Upon release, many fans compared "Lalalilala" to April's former labelmates Kara's sound, pointing out the song's grand chorus.

Promotion
The group started promoting "Lalalilala" on April 23, 2020, on Mnet's M Countdown, followed by performances on KBS's Music Bank, MBC's Show! Music Core, and SBS's Inkigayo.
