Bon Jovi 的演奏和创作能力在第二张专辑《7800 Degrees Fahrenheit》中都比上张专辑进步许多，与并不算太成功的首张同名专辑相比，这张专辑的金属气息无疑要浓厚得多，键盘不再是主要乐器，只起到烘托氛围作用，而主奏乐器——吉他则大量采用了失真效果，而且其演奏方式也完全是重金属式的；Jon Bon Jovi（Lead Voice）的演唱也较前一张专辑更有力度。不过总体来说乐队的表现还是没能逃出 Pop Metal 公式化的套路。但《7800 Degrees Fahrenheit》使 Bon Jovi 获得了第一张金唱片（50万张），更为他们以后的巨大成功打下伏笔。专辑中较为出名的作品有 “In and Out of Love” 和 “Hardest Part of the Night” 等。

Bon Jovi's sophomore release found the New Jersey group continuing with its engaging mix of hard rock dynamics and blatant pop-metal overtones, and primed the pump for the coming popular explosion of Slippery When Wet. Ever since the keyboard call to arms of the breakthrough "Runaway," Bon Jovi had understood that real success lay in a billowing smoke, soft-focus derivation of true metal, where Journey-style synthesizers and soft rock chorus vocals were the name of the game. To that end, 7800 Fahrenheit tempered its black-leather rock & roll with a rudimentary form of the sound that would make Bon Jovi superstars. They puffed out their chests for the groupie-groping, Mötley Crüe-style catcalls of "In and Out of Love" and made sure "King of the Mountain" rumbled with boys-night-out bravado. But they seemed much more comfortable with the twittering ballad "Silent Night" or "Price of Love," where arena-ready riffing met smoke machine keys and vocal trills. There was even "Tokyo Road," a valiant attempt at the epic scope of Springsteen that featured a Japanese-language intro and full-on character development. It was in these moments -- when the tenets of metal tried on the hairstyles of pop -- that 7800 Fahrenheit burned its brightest; the professional songwriting and increased cash flow of Slippery When Wet just made the existing mercury burst.
