Playing solitaire with cards. No talking. I haven't played for a looong time so probably a lot of mistakes... (decided to release this a bit early as I have a few other videos waiting to be posted too ;) )
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).
