It should be obvious that any genre of *well recorded* music will benefit from a good sound system (even if it's great sounding music you don't enjoy). But as mentioned previously, during the worst of the Loudness Wars, there were many excrementally mastered recordings compressed to near black hole levels. Sadly, I have a few of those that are really great (in my ears) *music*, and sound great in a noisy car, or via .wav file on half decent headphones, on a plane (as they were intended to). But on my main system where the lack of dynamic range in the recording is so glaringly apparent, there really is no benefit - more of a deficit in enjoyment in fact.
But, listen to Black Sabbath's eponymous album, or Rush's Caress of Steel where the recordings are good and the dynamic range is not squashed, and yes indeed, they really benefit from better playback gear with greater dynamic range capabilities. And for Symphonic Metal (e.g. Epica, Nightwish, Evanescence, Within Temptation, etc.) which I listen too ~50% of the time, especially the live recordings with full symphonies backing, the better the playback system, the better they sound. YMMV of course.
