1) Reading poetry is really enjoyable. To this day, if my son asks me to read to him, I'll probably try to read poetry. It just feels so good to read.
2) There are certain books that I really enjoy reading aloud and others that I don't. And its not the content, but just the feel of the words coming off my tongue.
Concrete examples, my favorite children's book to read is "The Little Island". Even thinking about reading it makes me feel a little happy. A book that I don't like to read aloud, but like the message, is "The Little Engine that Could" (this version https://www.amazon.com/Little-Engine-Could-Original-Classic/...). I found it a chore to read that book out loud.
