::::I see what you mean with consensus, but sometimes editors will support something because they personally agree with it, not because they think it goes with wiki standards. In some particulars, there isn't any need for consensus, or consensus will be based around a handful of editors who are arguing for their personal preference over real guidelines. 
 ::::I'm not saying that's necessarily the case here: just that sometimes acting against "consensus" is the correct thing to do, because the consensus will be old/based on misinterpretations of how things work. I've seen too many consensus' based upon opinion rather than sources to really have much faith in them. 
 ::::In this particular case, maybe consensus was just based on lack of sources/old sources. As things stand, it's very clear that the sources agree the band should be termed "gothic metal" and "gothic rock". Alternative rock and hard rock also have reasonable sourcing (and neo-glam, but as this has no article I don't think there's much we can do about that), so in those cases I'd like to hear what others think: should they be added? As it is, I'll go ahead and make the infobox reflect the genre section of the article in this respect, and see what comes up here for the rest.
