I take it I'm the only one who likes Daniel Johnston?
Oh, and
http://www.youtube.com/watch?v=t59QTEWtTJoHe wrote some really great songs. That's why people like him. Think about a guy like Leonard Cohen. He wrote some of the best lyrics ever written. At the same time (his first few albums aside) his actual music is the most awful thing you'll ever hear. Same kind of thing. I don't think anybody thinks (at least they shouldn't, because he isn't) Daniel Johnston is an amazing singer or musician, just like nobody (should) think Leonard Cohen falls under one of those categories. But they have the ability to write some great; and sometimes not great songs.
Daniel Johnston was crazy, and that's kind of what's charming about him. He has a crazy approach to music and especially back in the early 80's when he was getting his music out there, it was something new and fresh.
