Genie:us

Genie:us is the eighth Korean-language mini album from South Korean boy band Pentagon. It was released on March 27, 2019 by Cube Entertainment. The album consists of six tracks, with "Sha La La" serving as the album's title track. This is the first Korean-language EP the band has released as a nine-member group, with original member E’Dawn departing the group in late 2018, as well as the first album not to involve E'Dawn in any capacity. Member Kino did not participate in stage promotions for "Sha La La" due to an ankle injury he suffered in January. Starting on April 16, 2019, the group promoted the song "Spring Snow" for a week, for which Kino was able to participate in.

Name
The album name is a portmanteau of the words "genie", from the story of Aladdin, and "us" to create "genius". The title of the project has the connotation that "all people have talents that make them genius in their own field".

"The title of the album has dual meanings. First, it aims to give the confidence that we all can be a genius. The other reflects our wish to become a genie from a magic lamp."

Musicality

"When we staged our first album during a (local) music competition show, we almost broke the floor. We made a crack on the stage because we were so full of energy and ambition... We want to bring back the vigor, passion and confidence with this latest music. That's the whole point of this album."

Songs
"Sha La La" is a future house track with elements of hip hop and rock. The Korean title (신토불이) is an abbreviation of the phrase "신나는 토요일 불타는 이밤", which translates to "let’s light up this Saturday night". The song contains witty lyrics and dynamic dance sounds that aim to ease stress. Billboard highlighted the track's "vibrant soundscape that puts the emphasis on Pentagon’s multi-faceted vocal delivery". Leader Hui said, "You might have moments of stress and feelings of suffocation on your way from work and in school. I wrote the song to resolve them".

"Lost Paradise (Hip Hop Unit)" is a dark hip hop track sung by Hui, Yuto, Kino, and Wooseok, all of whom wrote and composed the song. The members tell their past selves that they are too young to be worried about failure. The tracks spreads the hopeful message that, regardless of one's struggles, a paradise exists within one's self. "Till... (Ballad Unit)" is a ballad sung by Jinho, Hongseok, Shinwon, Yeo One, and Yan An. The piano sounds at the beginning and the full band towards the end enhance the song's theme of perseverance. "Alien" is a witty hip hop track wherein Pentagon expresses their wishes to become a group with a unique, alien-like personality. "Spring Snow" is happy, exciting alternative rock song about the group's experience during the spring of 2018. In the final track, "Round 1", the members playfully diss each other with inside jokes. Every member of Pentagon had a hand in writing and producing the song.
