I'm currently going through that one torrent of "The top 100 Sci-fi" audiobooks. There's a couple so far that I've skipped through:
Stranger in a Strange land (When it develops into a weird sex-cult thing, though I like the word Grok)
Anything by Heinlein after Starship Troopers
Some Kurt Vonnegut (Though, I may read Slaughterhouse 5 one day)
The Left Hand of darkness just seemed like Feminism: the book
Lord of Light: I get where he's going with it "could it be fantasy, could it be sci-fi", but wasn't interested.
I think that's it for now. I just got off a binge of 31 of the 41 Discworld books and am looking for something else. (I started the Witcher books in chronological order)
