Hi, I am sorry this month has been more full videos rather than bloopers, I do have the bloopers to this as well which I will post. I just wasn't keen on this video so don't have the confidence to upload it to a big audience. So I hope you can enjoy it here instead.
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).
