So now we're a couple of days out from the release of Zune 4.0 and folks have had a chance to try the new, updated ecosystem -- albeit with a few glitches here and there and a total bug-squishing session with zune.net. But just for a second I wanted to talk to you guys about the Smart DJ and the Quickplay portion of the software.

When I first looked at this screen, I thought that the "history" and the "new" sections of Quickplay were welcomed additions. Then I stared long and hard at the pins part. What the hell was I going to put there? I know it can be essentially any media in my collection, but do I have anything that's worth pinning? Is there anything I have that I absolutely need to see right off the bat when I open my software? Would it have been better served if there was a place called 'continue' where it was stuff you started but didn't finish?

Then I began to try and pin stuff: One of my favorite episodes of To Catch A Predator, Seal's debut album, etc. I couldn't tell you how many times I pinned something only to pin something else in its place about 2 minutes later. Could that just be a testament of how great my overall collection is or do I just have serious A.D.D. with this thing? It was the same situation I had with the favorites part of Zune Social. I couldn't just have 8 favorites, I needed 80!

It's the same thing with Smart DJ. I was enjoying the feature so much that I was swapping out artists in those 5 slots in Quickplay. Luckily you can start Smart DJ from anywhere in the software, but in choosing to have Quickplay as my opening screen I wanted to use it for its intended purpose and have some great content at the ready when I arrived.

So I guess what I'm asking is, what are your impressions of Smart DJ and the whole Quickplay screen in the software? There's been many positive comments about Smart DJ on Twitter with folks saying that they started it expecting it to last an hour and ended up going to sleep with it still running.

Has having a pins segment caused you to change how you look at your collection as a whole? What's your criteria for which media gets the honor of being in a PINS slot?

Do you care to share which artist(s) were your inaugural Smart DJ artists (or songs/albums, if applicable)?
