I actually was going to ask about the soundtrack for the series: the music adds to the enjoyment of the show, and I think of it as being an alternative narrative, very dramatic and moving. Is there a CD, or at least a playlist of the music used in the series? For those who have had a hard time hearing the narration, try using headphones, which will amplify the foreground sound. I use them anyway to hear my TV over the background noise in my own home.
