I listen to a heap of podcasts, in fact. At work, I generally can't listen to music with words so I stick to trance podcasts, but during my walk home I'll listen to all kinds of ones with speech. This ranges from actual spoken ones, to heavy metal ones with lyrics, and ones with both.

Off the top of my head: 99% Invisible, Freakanomics, Trade Talks, Requiem metal podcast, Still Untitled.

Audio books are probably worth looking into, too. I tend to put aside 30-60 mins in bed reading before I sleep, so I tend to consume enough literature that interests me, but it's definitely a good idea if I want to expand on that. Thank you!
