"Rush Hour" is a hip hop-EDM song expressing the plethoric nature of the K-pop industry as heavy traffic, "Autobahn" is a song with club-ready electronic beat, "Ride with U" is trap beats meet the faintest trace of funk song, "Got Me in Chains" is a song with striking layers of techno and R&B, "Just Love" is a gentle meld of pop and R&B song, "Mercy" is a dark and foreboding song with gothic sonic elements, and "I Got Love" is a generic blend of trap and hip hop song.[1][2]
Reviewing the EP for NME, Carmen Chin showed that it upholds the group's ambition "to unashamedly evolve into musicians who break barriers" and it delivers "quality music shaped by the very hands of Monsta X", with all the tracks "flaunt[ing] either writing or production credits from two or more members of the group at a time".[2]
