La Di Da (Everglow song)

"La Di Da" (stylized in all caps) is a song recorded by South Korean girl group Everglow for their second extended play -77.82X-78.29. It was released by Yuehua Entertainment on September 21, 2020, as the EP's lead single. It is a synth-pop-inspired song that delivers a dismissive message to haters. It was produced by Ollipop, with whom the group has been working since their debut, and co-written by member E:U. The song was named the best K-pop song of 2020 by Billboard on a year-end list.

Background
On September 12, 2020, the group officially announced "La Di Da" and the other three tracks on the EP. The teaser for the single's music video and multiple concept photos were released on the group's official social media accounts, revealing the retro style of the comeback. In the showcase event for the EP's release, member Yiren said, "We tried a bolder and more unique performance…We also tried to expand Everglow's musical spectrum."

Composition
"La Di Da" is a retro-inspired uptempo electropop song that combines various elements from the '80s, such as cheerleader chants and strong synthesizers. The lyrics have a strong sense of self-empowerment and sends a humbling message to the "bad guys" and the "players" (haters). The song was composed in the E♭ minor key with a tempo of 160 beats per minute.
