In all honesty I think your post is fucking idiotic 
Unabridged audio books are great and it doesn’t really matter how highbrow the book is, although I’m not sure why you think Slaughterhouse V is some kind of apex of literary genius that ASOIAF isn’t. They’re both enjoyable, quick writing.
I used to listen to these all the fucking time as a kid. Meant I could digest books while playing computer games (this was the 80s so we’re not talking the full-3D type stuff you get now) or doing drawings and stuff.
