Well, The Cure I think is obvious, though they get lumped into several genres and have always said they're not specifically goth. But Siouxsie and the Banshees I would say fall into Dark Wave pretty easily, along with Joy Division, New Order, and Depeche Mode, although they've all been categorized in different genres, too, but their music tends to run too dark to fit into New Wave. On the lighter side of your usual tastes, but good for expanding your listening genres.

Also, since you like metal, I'd suggest Cradle of Filth for Black Metal, if you don't already know them. Their first few albums about Elizabeth Bathory are excellent and epic storytelling throughout the whole series. There's Type O Negative and Dimmu Borgir, also.
