Not properly tried this before, but I'd imagine if it was interesting I'd want to stay awake and listen to it or find out more information... if it's boring I'd just be annoyed by the noise. Maybe bore myself to sleep?
I prefer science and history, not stories or news. Interesting enough to engage you, but not too much. Science Friday or Sean Carroll's Mindscape are good examples. Anything you find that lets your mind disengage and wander around bedtime. Make sure you have a sleep timer that stops after 30-60 min and/or turn off autoplay.
