Rolling Stone review
Eighties pop-metal gods pair with Swedish master producer. Do not try to resist. A couple of years ago, a band named Bon Jovi put out an album called Crush that was intended merely to promote some live shows overseas and pay off a few mullet-replacement-surgery bills. Instead, the recording became their first American hit in years, thanks to the single co-written by Swedish popmeister Max Martin, "It's My Life."
Naturally, their fellow Eighties hair-bangers sat up and took notice. So X is Def Leppard's own version of Crush, complete with a Martin power ballad.
