The album spans several genres, including nu metal, heavy metal, and alternative metal. Sputnikmusic said that the band takes "take the sound they established on their self titled debut and push it in a darker and, on occasion, more humorous direction." Tower Records said that the album was "full of shrilly, distorted guitar squeals, bass-heavy darkness and laryngitis-inducing growls," while considering the album to mix the genres thrash metal, hip-hop, punk rock, funk, and humor.
Q Magazine said that the album was both harsh and hard, and Stephen Thomas Erlewine of Allmusic said that the album's rhythms were "straight out of underground black metal," while also noting that it "enhanced their metallic influences." With the same band-line up as their previous album, Korn, the band created an album cosidered to be darker than their debut album. Entertainment Weekly considered the album to be of interest to "mental-health professionals." Jon Pareles stated that the album's themes characterize that Korn is "Mad at Everybody, Including Themselves," and considered his feelings for Korn were mutual. iTunes said Life Is Peachy was "a barrage of throttling, detuned guitar aggression that erupts from the bottom like molten lava."
