Death Metal, I can see as one. Lots of dark lyrics, hard beats or eerie sounds; I guess anything with that could be considered "goth music" in its own merit. Dark Ambience is a definite Goth thing; and Marilyn Manson's music strikes all as Goth.
Now with that out of the way, no. I am not a Goth per se; but aspects of the style keep me interested. Black goes with almost anything, Metal is the best damned music around, Dark Ambience helps me to sleep, I'd love to have my room painted either black or navy, and night is my favorite time of day. Correct me if I'm wrong, but I think that only makes me psuedo-Goth; due to my tendency to wear white and blue, as well as my generally chipper personality and such.
