For years now I've been falling asleep to documentaries on YouTube. Mostly about space or military history. The often monotonous tone of narration usually lulls me off quickly.
The draw back is if I find a particularly interesting one and get to focused on it.

I use my phone and disable autoplay. I just let it run for an hour and than it'll turn off.
Hell on the internals in the long run though.
