My baby is busy wrecking people in wow pvp, but I thought perhaps kayboard sounds could cater to the video? Ehhhh? Anyways. Your plexi glass video is coming everyone, but imma keep throwing some hand movements your way in the mean time :)
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).
