Open Audio file in the same window / Set icon for audio-files

I would really appreciate to be able to:

  1. Set an icon for an audio file, instead of the file URL which looks really ugly and doesn´t invite the user to access it.
  2. To open the audio file in the same window and not open a new one by default, which only shows a black page with the audio player in a small size.
    Thank you!

I would like to see this too:
