Rover (EP)

Rover is the third extended play by South Korean singer Kai, released on March 13, 2023, by SM Entertainment. The EP contains six tracks including the lead single of the same name. The physical album is available in five versions (two "Photobook" versions, one "Sleeve" version, one "Digipack" version, and one "SMini" version).

Background and release
In February 2023, SM confirmed that Kai plans to release a new solo album. On February 17, SM announced that his new EP, Rover, would be released on March 13.

The music video for "Rover" was inspired by two movies: Billy Elliot (2000) and Catch Me If You Can (2002).

A promotional video entitled "FILM : KAI #Rover" for the EP was released on Exo official YouTube channel on March 20, featuring performances for each of the EP's b-sides.

Composition
The lead single "Rover" is a dancehall song featuring heavy bass, marimba, bells and various percussions. The lyrics sing of throwing off the restraints of others' viewpoints and living freely as a 'wanderer'. "Black Mirror" is an R&B hip hop song with lyrics that question the lifestyle of modern humans reliant on the stimulating, provocative content on social media. "Bomba" is a dance genre song with reggaeton beats. "Slidin'" is an R&B soul genre song that features elegant arpeggio synth sounds and rhythmical drums. The lyrics compare falling in love at first sight with someone that you run into by chance to one's clothes becoming wet from a sudden downpour. "Say You Love Me" is a hip-hop R&B song accompanied by drums and 808 bass. The lyrics make use of candid, straightforward expressions to depict one's desire for the other to confirm their interest in an honest manner. "Sinner" is a pop genre song with piano and synthesizer as accompaniments. The lyrics express the desire to remain trapped in an exhausting type of love where both exhilaration and pain coexist.

Commercial performance
The album debuted at #1 on the Circle Weekly Album Chart (March 12–18) while the lead single Rover topped the Circle Weekly Download Chart in the same week. The album topped the iTunes Top Albums chart in 40 regions, including Brazil, Mexico, Argentina, and Chile. Additionally, the lead single Rover debuted at #12 on the Billboard World Digital Song Sales.

Reception
David Opie from Paste named Rover the 10th best K-pop album of 2023, who praised the record's production and sensuality. He named "Bomba" and "Sinner" as the EP's standouts.
