Big YouTube ASMR channels (with ad blockers to prevent loud interrupting ads)

Audiobooks in a language you don't understand yet but like the sound of (listening to the sounds rather than the story so nothing lost by losing your place)

I've been listening to YouTube videos of someone talking about Marvel Snap, which is a game I play. I think one person is better than a conversation, less likely to get loud. And you could pick something you like of course. I think games with regular updates are good so there's always more content to listen to from videos.

What will probably not work for you but I like:

Forensic Files, starting from S1

Simultaneously soothing and mindless

Prank phone call compilations are inspiring for the sleep! I like the touch-tone terrorists and the nephew tommy for some good sleepy bedtime audio snacks!

This History of the English language documentary puts me right to sleep

Listening to math videos that are somewhat interesting but in the end unimportant (to avoid conditioning yourself to feel asleep when studying real math)

Listening to white noise

Old crooners, like Engelbert Humperdinck 😁
