This is one of Def Leppard's best albums ever. "X" is a cross between the huge harmonies, the catchy melodies, and pop-worthiness, of "Hysteria" and the "I don't care what anyone thinks, I'll play my music the way I like it!" attitude of "Slang". I've been a fan for over 21 years. I've grown up buying every Leppard album the moment I see it in the stores - whether I've heard it or not.I don't believe that Def Leppard has ever made a bad album. "Slang" is actually my favorite. Now it's a toss-up with "X".Do yourself a favor and buy this album! You won't regret it!!
