Angel of Retribution, the group's big comeback album in 2005, is much better than you'd expect. Standouts:
"Deal With the Devil" (classic '80s-style metal, but doesn't sound dated at all).
"Revolution" (a lot like Queen's "We Will Rock You", but even more Badass).
"Worth Fighting For" (a lusciously melancholy cowboy/Western-style number, with a Buck Owens-like riff and Rob singing in a decent American accent; he even sounds a bit like Scott Weiland of Stone Temple Pilots!).
