Actually, I like Gillian Welch's idea that record stores should just have one category and line everybody up alphabetically. Never had much use for pigeonholes, myself. If asked what kind/category/pigeonhole my own stuff is, I don't have an answer except to play the music and let people enjoy it; whatever they might choose to call it is their problem, not mine.

You have, of course, noticed that when a "folk" artist (Shawn Colvin for example) sells a lot of copies they get "moved" into country or pop. God forbid anyone should admit that they like folk, or that an (f-word) artist made a popular record. I tend to like the artists that find the space between the categories.
