I left a custom tailored leather jacket on a flight from ORD-DFW last week and by the time I got back to the gate the plane had already turned around to ORD.
I called ORD lost and found and got a recording that said "If we find your stuff and don't like it, you can have it back. Otherwise, we won't call and don't you bother calling us back either..."
Since fewer people can use my jacket than your ipod, I think you need to buy a new one.
I am already planning a trip to Bali to get a new jacket made...
