Music OSD during picture slideshow screensaver?

I'm looking for a way to activate the same music OSD during music visualisation (albumart + controls slide in from left or bottom) displayed during screensaver.

If the screensaver is activated (slideshow of images) the music osd is not displayed (when the song changes).

Is there an easy way to do this? Copy some code from musicVisualisation.xml to slideshow.xml? Can this be done? I was looking at the tag 'MusicVisMediaInfoVisible'...
