wow - this just brought me back to a zune subscription.  in the past when i went through periods of wishing i actually owned some of the songs i had synced to my zune i had to decide whether to pay an additional amount, but now included with the zune pass subscription, you get to keep 10 songs per month.  check it out here. also the new common album is almost here, so now i know where i'll check it out and obtain it!
