As I've said, I am not an authentic fanatic; I lack grit. But I spend a lot of time thinking about fanatics and I've concluded that the following 10 artists have the most dedicated, least rational fan followings:
1. Slayer
2. Tori Amos
3. Sublime
4. Kiss
5. Bruce Springsteen
6. Black Sabbath (particularly the Tony Martin era, for some reason)
7. Jimmy Buffett
8. Iron Maiden
9. Guided By Voices
10. Morrissey
