There seems to be a little bit of confusion on ye olde internets about videos produced for Zune, like the recent Zune TV spot. In the realm of videos for Zune, we did two things: advertisements and Zune-arts. We produced a series of videos - like "Picnic," "Battle," and this week's. Those are our advertisements - shown on TV in top markets.
Separate and independent from the advertisements, there's the Zune-arts program. For that program, we partnered with folks in the creative community, and asked them do an expression of the Zune brand: all about music, entertainment; friendship and sharing. Like Endless Cookie (my favorite).

There's more about Zune-arts in this interview Thomas and I did last October. So to sum up: Zune-arts: partnership with creative folks, not advertisements. The actual Zune advertisements: here.
And lastly a few folks have also asked about downloading the track used in the latest TV spot - "This is Why I'm Hot (Rock remix)." The song isn't officially released yet - when it's ready, I'll be sure to post about it.
