How about podcast binges?! Some of my favorites are Reply All, Radiolab, Reveal, and You Are Not So Smart. And of course, Serial (and its spin-off, S-Town), Someone Knows Something, and In the Dark are all great for following a single story throughout m,ultiple episodes.
And, I know this might be a super unpopular opinon, but I used to really like My Favorite Murder. But as time went on, I found it to be more and more exploitative and voueryistic than informative and I just started to feel not so great about listening after a while. I guess I find it too difficult to suspend my humanity long enough to enjoy it!
