I have found that I like podcasts that act as readalongs.

My favorite: Let's Get Weirding. They have done: Dune, Dune Messiah, Children of Dune, and are working their way through God Emperor of Dune.

Other ones:

• Chapter by Chapter
• Gom Jabbar (Also has deep dives on specific topics,
• Reading Dune (Dune and Dune Messiah only to Chapter 24
• Pod Emperor of Dune (Dune, Dune Messiah, Children of Dune, God Emperor of Dune, Heretics of Dune, and Chapterhouse Dune).

Other ones that are cool:

• The Dune Saga Podcast (Take on whole books at a time, includes ALL 23 books
• The Dune Podcast (16 episodes, gets into the meat and bones of the making of the Dune movie
