This is a bummer, just the other week when I took my 2004 Mustang Cobra out for a spin my Zune mp3 player broke. I'm not positive why my Zune died, but I think it may be the battery. I thought the batteries would last longer on a Zune, it's only been a year and two months. I guess if I'm using it like every other day when I workout and driving in my muscle cars, I can see why the battery wore out. It just sucks though because it's warm out and I'm driving around without any music. I just hope it's the battery, if it's not, another $100 or so will be spent on a new MP3 player. Man I wish MP3 players would last longer!
