Feature description

When pressing the "pause" button while a song is playing, the music is faded out very quick. Similar to pressing play, it is faded in very quickly.
I would like to have a longer fading time, e.g. via a settings option.

Why do you want this feature?

I want use my phone to play ambient music on a stage during performances, and want to stop playing the music when the current performance ends - but not as abrupt as it is now. The music shall slowly fade out.

Additional information

• Poweramp supports this feature, but only up to 1s fade time.
• Reddit thread is there a music app where you can adjust the "fade out on pause" duration?
