I usually don't listen to music and read, unless it's either instrumental or the words aren't in a language I can understand. Prime examples are Karl Jenkins, E.S. Posthumus, etc. Also, Blackmore's Night is fantastic listening for when I'm not reading, Leinton. Good choice. I do, however, almost always write to music, so there's that.
Even though I didn't listen to it while reading the book, the album Cartographer has always reminded me of Warbreaker for some reason, particularly the Piri Reis disc. Perhaps it's because of the Atlantean feel I associate with the book, but I was wondering if anyone else has noticed this as well (and if you've never heard anything off that album, YouTube it! You'll be glad you did).
