Hey everybody, hope you’re all doing amazing and I hope you all really enjoy this video and I hope the audio is OK. Thank you so much for suggesting this video and giving me great ideas for me to continue making videos. 
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).
