If a book (mentioned anywhere) looks good, I have just started getting it on audible.
If I start it and do not like it, I simply return it. I think returns must be done within a year of purchase.
So then I always have a few books in queue, ready/available.
It is rare that I see a book reviewed or mentioned in a podcast and think “that sounds good”.
Most often I think the opposite.
If it is a classic, many times I have already read it.
So when a title does sound good, rather than putting it on a list, which I might forget I even have, I simply use an audible credit and put it in my library.
