Disable screensaver during music playback

(Original thread here: http://forum.xbmc.org/showthread.php?tid=125524)

I use the Slideshow screensaver to display my pictures when XBMC aren't used - and this works perfectly as intended. When XBMC aren't accessed for the desired duration, my pictures start displaying. And when I play music, XBMC displays the music fanart in the background with Now Playing information. This is also what I really like.

Now - the problem is, that after the music have played for some time, the screensaver kicks in, and the fanart is no longer displayed. Instead I get the Slideshow screensaver with a smaller Now Playing information.

Is there any way to disable this behavior?
