Note: I didn't realize until after I posted this video that the editing software did some weird stuff to my video segments. It randomly took little parts out and added transitions that I didn't want. I apologize for that, and I'll try to redo this video when I get home from work this evening. Peg tries to help Edward with his scars...
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).
