Do you have to be pretentious to post here?

Probably, I guess

I like a lot of the music that Sean Breadin posts on youtube and myspace, and I also think that he talks a good deal of drivel.

That's fair enough, I can only manage the latter.

Whether his music is 'psych folk' or not is questionable, but as I couldn't define it, what's the point?

It does seem that some people have mistakenly regarded the term 'psych' as meaning psychological rather than psychedelic

Anyhow, each to their own, and lets throw away some of the stylistic boxes that we like to force people into.
