On account of 1Q84, I went and listened to Janacek’s Sinfonietta - six months after I read the book - so that one evidently stuck in my mind. I’m not sure I could identify the piece in the first few bars, however.

The 50 Shades books. Picked up the first one as a joke so I could make fun of how bad I knew it was going to be.

Three back to back books later, the joke was on me.

This is my thought too.

OP - I think you just found what you like and what you don’t like. Nothing wrong with that.
