Interesting thread. The feeling I get from the whole "Goth" thing is that it is really a lifestyle for hard core fans. The $$$ point is a valid one, as I own a small recording studio, and have been in the recording bizz for 15 years....believe me, as pure and honest the musicians seem to be, money is a huge part of it, as it has to be! They do it for a living!
Although I have never been impressed by the playing or songwriting of the "goth" bands, there are good ones and bad ones, just as there is "Good" rap and bad rap.
One last word on rap, most has no melody, so it is really not "music" by definition.
I'm a song guy, need a song!
