I wonder through isolation how much of this is just wanting to listen to other people?
When I'm doing serious work, I (maybe counter-intuitively) often put on a lighthearted/silly/dumb comedy podcast, and it serves well as background noise. I don't feel any need to pay close attention or rewind if I missed something.
When I'm doing a slow, rote, boring task, or something not too important or mental energy-consuming, or if I'm just in the mood, I put on a hard science or philosophy podcast (Lex Fridman, Sean Carroll, Eric Weinstein) and listen pretty attentively.
Same reason why news readership has gone up a huge amount this week
