While the lyricism of "Charge!!" continues in the typical Aquabats tradition of comedic self-referential narratives and pop culture and geek culture-oriented satire, the music introduced a bold new sound for the band, featuring a predominant focus on guitar and keyboard-driven rock, punk and Devo-influenced new wave rather than the ska-driven eclecticism of their earlier albums. Notably, "Charge!!" was the first Aquabats studio album not to feature brass instruments, indeed one of the most remarked upon aspects of the album by reviewers; in a 2006 interview, Jacobs stated that the band attempted to write a saxophone solo into one of the album's songs but ultimately felt it sounded too out of place.
