Hello, Here is my take on this. Lets assume for a minute that the MediaPlayer would halve to be running to keep the music playing. This would indeed require that when it goes to the background it keep running or music would be lost. I would suggest having optional event handlers in the JavaScript that would allow apps to deny sleep mode or request a working level of sleep. Maybe the app would request that it continues to have access to media controls.
But here is the other halve. The MediaPlayer isn't required for the media to be playing. The Media playback would be handled by a Native background process that would only be directed by MediaPlayer. There is no need for MediaPlayer to be active if the playlist is set and the music will just keep playing. I'm sure a lot more thought could go into this but I think of the web app to be only active when a user is using it. I would be interested in any arguments that would require the web app to be active when the user isn't interacting with it. I believe most of this could be handled with useful event handlers.
