Nothing good gets written without the writer suffering along the way, in my opinion. Writing should be a pleasure, but unless you feel almost broken many, many times in the journey to a novel, you haven't pushed yourself hard enough.
Basically, asking me what kind of music I like is like asking what kind of food I like: 'Anything that tastes good,' is the answer. I'm the kind of guy who spends three times as much on his speakers as he does on his television.
