The music is worth listening to over and over again. I have done* and, eventually, at some time in the future, I might make sense of it. The book, however, made sense straight away. Because I understand the world through words, through writing, specifically.
Even though I play music, and I have a voice when I play, my first language is the written word. When I speak to people, it never comes out as well as when I write it down, and when I listen, it never makes as much sense to me as when it’s written down.
*Amazon tells me I last bought the album in March 2017. Can’t even remember buying it, (how do you lose an album? They’re not small).
