I dont know if anyone mentioned this already, but The music from Chapter 6 and 7 where Budd is talking to Bill and then comes back to the trailer at night is from a great giallo called The Strange Vice of Mrs Wardh. If you get the DVD you will hear the score by Nora Orlandi.
I love how QT put eerie giallo music in the chapter thats supposed to be like a spaghetti western. Hes the master.
