Zune Software's Screen Saver

I bought an album through the Marketplace the other day which has revealed to me a previously unknown feature of Zune's screen saver. Instead of giving me the usual collage of album art, I got a screensaver much more like I get on my ZuneHD - a slowly zooming photo of the band (Depeche Mode in this case) with lines of relevant text scrolling across at different angles. I have been using Zune for nearly two years now and I have dozens of artists on my device with photos, so how come this is the first time the software has done this? I've also bought plenty of stuff through the Marketplace and I've run Zune Social Tagger but this is still the only album that uses this kind of screen saver. And the really weird thing is none of the other Depeche Mode albums I have bring up that screen saver, they just get the standard one.
