Playlist Player shows incorrect Big Playbutton animation state when the 'next' track auto plays

[ofsound]

Instead of showing the Pause state, it stays on the blinking eyes loading animation despite the track playing in the big player.

This seems to happen most of the time on any playlist on alonetone.com with Mac browsers, but sometimes it works perfectly ( maybe more so in Firefox ). iOS on the phone seems to have the same issue.

And in this same state, the animation that darkens the waveform happens in spurts instead of continuously updating left to right. And then seek on this new track also seems erratic.
