I wanted to make this video a short, but it was too long 😭. So, I just uploaded it as a regular video 😮💨. Sorry about the filming being vertical, but I can't really fix it.
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).
