Yeah, I hear ya, I do like to have a book in my hands (or at least text on a handheld screen) if I’m trying to internalise all the information in my first read through.

But I do tend to use listening to theory when I want to drift off from it and just want the effects of having to listen to something that dense, with the understanding that doing that as a sleep aid or for other emotional or physical effect is not a replacement for listening attentively or actually reading it.
