Mustaine pointed out that four of the album's 12 tracks are "fast, hard and crunchy". Referring to the musical direction of the album, MTV's writer P.R. Flack noted that "The Disintegrators" and "FFF" were rooted in the thrash metal genre, and ranked them among the fastest tracks on the record. Neil Arnold of "Metal Forces" highlighted the tune "Vortex", which according to him, features some of the album's best guitar work. However, a number of songs, particularly "I'll Get Even" and "Use the Man", carried a more rock-oriented sound, which contributed to the album's diverse style. Lyrically, the album does not have a distinct subject matter, but focuses on numerous themes instead. "She-Wolf" tells of a "wicked temptress with mystic lips and lusting eyes", while "Mastermind" has been stated by Mustaine as being about "the computerization of the world."
