The band's first five albums blended the glam metal and hard rock genres. Their first two albums used a heavier mixture of glam metal and hard rock while their follow ups, "Slippery When Wet" and "New Jersey," featured a more commercialized mixture of glam metal and hard rock. They made a "more serious interpretation" of their pop-metal sound on, "Keep the Faith". On their sixth album, "These Days", they utilized a more mature hard rock sound. "Crush" was characterized as "far enough into pop/rock to actually stand a chance of getting airplay", while "Bounce" was described as "heavy, serious rock." "Have a Nice Day" was also characterized as being heavier than "Crush".
