I don't really write the sort of thing everyone else does. I recognise others who work in similar fields to mine, but I do a lot of different things. People have said I'm an original writer, but this may just be perversity. I'm certainly as influenced by film as literature, and I have an eclectic taste in music, which does indeed feed into the work. When writing stories or novels set within the last century, I dig out music appropriate to the time and place and play it while I work, whether it be the Velvet Underground for a story about New York and Andy Warhol, or Nino Rota for a story about Rome in 1959.
Popular music is often associational, which helps.
The manager of the shop where I buy CDs has remarked on the breadth of my interests. I had good teachers at school, college and university. You've stayed with the same publisher for your novels, if not for your film books. I'm happier with them than many of my writer friends are with their publishers. I live alone, but in the middle of a city.
