Destiny Turns on the Radio

I guess I must be a bit odd, but this movie represented so many important things to me - Destiny (soul mates), Las Vegas (I was drawn to this city and love it here), mysticism/magic (the gold pool, the coyote, the Marilyn Monroe Motel (like the 'Blue Angel' here in Vegas), and the music - Just My Imagination, always a favorite by the Temptations, and here played by Booker T and the MGs, added just the perfect touch for the two main characters' love scenes. (Plus Louis Prima's Old Black Magic at the end, was perfect for many reasons.) Also, the quirky humor was great - Pappy's sincere discussion with his son about the 'peneal gene', and how 'prisons make him nervous', and his greeting to his new daughter in law. Loved Thoreau's scenes too. I agreed, Quentin Tarantino's role in it was enigmatic, but not 'quite right'. I had the feeling he would have rather played Julian's role. Question: how can I contact the writer and learn how he came up with the plot concept and the choice of music?
