From my experiences, people who were stout in their self-proclaimed goth status, saw themselves through their style of appearance more than what music they listened to. I've seen Evanescence and Cure fans called "goth" but not only did they never look goth, the bands themselves never liked the label even if they liked the people.
"Goth was like pantomime to me. I never really took the whole culture thing seriously...Every goth I’ve ever met has been very nice, you know? As a subculture, I think it’s full of wonderful people. But I have never liked what’s classified as goth music.” Robert Smith
"Our original Web site like in the ‘90s was called ‘We’re not goth.’ [Laughs] But I understand it, and there are plenty of goth kids that are our fans too. I think goth is kind of a silly, outdated word. I think our music is rock, first of all, but then we incorporate a lot elements that make it dark. Nine Inch Nails is a big influence. Depeche Mode. The things I have always been into that have inspired the band have always been a little bit on the darker side. I'll call it dark, but I won't call it goth, because anyone who spends three hours putting on makeup everyday isn't really thinking about anything more than that" Amy Lee
