This is part 2! On nearly every picture was some name or place that I had never heard of before, so I'm pretty sure that I didn't pronounce anything properly, but oh well :P Xx Jolien
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).
