This is already my third visit to Bharti (inst @cosmas.bharti) since there were many requests to come back to her and I also enjoy her massages very much. As usual Bharti is giving comments on what she is doing and is telling some interesting information during the session. After the massage Bharti treated us with some Indian food that she cooked herself :)
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).
