Another very rough video. I edited this on Youtube with the lab's old computers, so it may not turn out as smoothly as I'd have liked. There may also be cuts in wonky places. Let me know if I need to fix something!
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).
