Music and Writing

I love Basil Poledouris's scores. However, I can't write to them. Not sure why that is, but it simply doesn't work. They're excellent around-the-house music, good reading music (though I don't usually listen to music while I read), good journal-writing or internet surfing music, but if I try to write fiction to them, I stay distracted and unfocused. Not entirely sure why that is, but it's rather interesting.
