Actually, Def Leppard still puts out some good music. Nothing will ever replace the pop-metal sound of Pyromania or Hysteria, but their stuff in the last few years is pretty good. "Slang" (1996) their only venture into grunge rock was pretty good I thought, and "Euphoria" (99) and "X" (02) were good also. Euphroria sounds like a more mature 80s sound, and X is a more mellow sounding Def Leppard. I still like the new stuff. Check them out. You might be surprised.

Of course, I am a little bit biased.
