Saw this recent list of SciFi that everyone should read --

Turns out, I've already been exposed to most of these, but I did find 3 that I haven't read and were available as audio format. The list is heavy on "classic" writers like Heinlein (way too many Heinlein titles in my opinion), Clarke and Asimov but makes attempts for more inclusive (and less problematic) authors.
One of the more recent authors I already mentioned in this thread, Becky Chambers and "The Long Way to a Small Angry Planet".
