:Does it have to say "unclassifiable" in the intro?  The article could always take the route of Green Day (also subject to genre debates) and just say  musical band.  The word "unclassifiable" just raises an issue which probably isn't that important in the greater scheme of the band's importance and notability.  Mind you I don't actually listen to HIM, and as such the word "unclassifiable" doesn't actually help anyone without a frame of reference with the band.  This seems more an issue which vexes fans of HIM itself.
