I think that it is a great option for listening to music while at work. I had a Yahoo music account a few years ago, before I had my iPod, and it was not as nice. We used Mozilla as a browser and it wasn't supported. I ended up not using my second year's subscription due to that fact.
Give it a try. I've linked it up, but it will open in this window. I really need to find that HTML code that I used a while back. Hmmm, perhaps I need a class?
