Wow, that sounds like shit. I use YouTube to sleep, though on Librefox with UBO and mostly the channel Good Sleepy Knight or longer talks.
Good thing with GSK is that their 7 hour static after 1 hour story seems legit and is, if anything, a confirmation to go back to sleep unless my lights have turned on if I wake up at night and hear it, and chill and real enough that I can focus on it to fall asleep easily again, without being too much to wake me up more.
