I am not sure if you're doing anything wrong.. I think it could be a
bug in the estimated remaining time on the track being faded out..

Is there a chance you could isolate a productible minimal script with
for instance a request.queue source an audio file that is known to not
work.. With this, I might be able to investigate more..
