So managed to pack my game into an app with phonegap, and after lots of experimentation I've figured out that making KlangM's gonna be a challenge since audio.playbacktime is only reliable for sounds in the sounds folder. Even when the music plays just fine, I see that the value itself updates much more rarely when placed in the music folder. This forces me to accept massive loading times in order to be playable on mobile.

music also won't loop seamlessly.
I've done a workaround where I play the music not looped, then On Finished, I manually restart it. Not great but it works.
this is mobile Cordova only on Android, have not tested with iOS.
