[MPlayer-users] play audio in window (gui)

[Thomas Keller]

when I open audio file from commandline, such as

  mplayer my_audio.mp3

mplayer plays the audio inside the commandline.

How can I tell it to open a window, same as when playing video file ?

I don't care what the window background would be, it can be all black.
But I need individual window for each audio file, so that I can switch
between them.
