Teen Gothic

I wanted to know what artists do you consider "true goth" as I've been trying to look up for that but a lot of people just says which ones aren't goth (Marilyn Manson, NIN, MCR) and I've even seen people saying that Bauhaus, Siouxsie or Sisters of Mercy aren't "true goth".

Edit: just to clarify, I'm not talking about the bands I've just mentioned. I'd like to know your picks on "true goth" bands besides the big ones.
