NOTE: I eat meat in this video, so if that bothers you, it's ok not to watch this. It's 9:00pm and I'm just now getting around to eating my dinner. Come join me with some reheated pork chops, Pepsi, and roasted pumpkin seeds. I'll give you the dirt on my (possibly hypothetical, maybe) neighbors and their shenanigans. Theoretically. :)
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
To listen with the screen fully off, in-browser playback stops by YouTube's design. Open the video in the YouTube app to keep listening where background playback is supported (e.g. with YouTube Premium).
