Someone said INFP at some point I think....??
Heh... I just had a flashback to my Syd Berret phase from highschool. I lost my first potential gf because in her opinion, "That music's eating your soul!"...
I want to say INFj simply because his lyrics are very reminiscent of the sort of thing I would write. Not really for content so much, but for the polished rythme and rhyme schemes. His behavior after being pushed out of Pink Floyd also strikes me as INFj. To just quietly disapear into his own little world like that, without really showing any animosity.
I didn't know that he died! Just read it in the paper... How sad
