What feature would you like to be added?

It would be nice to have some way to reliably detect the completion of audio playback, i.e. when audio.Player receives io.EOF while reading from its io.Reader.

Right now, I'm attempting to detect this state by repeatedly polling IsPlaying() and waiting for it to become false without me having called Pause() to intentionally stop playback, but this feels imprecise compared to e.g. having a channel I could read for events.

Why is this needed?

This would make it easier to start playing a new music track immediately after one finishes.

I think polling is the best way so far. I thought a method returning a channel might be a good idea, but an audio player can reach the end multiple times by rewinding, so a channel doesn't seem a good way.

Thanks for the quick reply! I'll stick with polling for now.
