Hmmm, I was recently involved in my own horror story, so much so, that I have cancelled all dealings with PayPal and eBay and will never again attempt to use either of them. My little saga lasted over a year!
The problems I had with a fraudulant seller on eBay were dealt with swiftly by PayPal and I recovered fully the money involved. However in your case it's a straight forward transaction error. If you didn't order the mp3 palyer you won't have to pay. Just to be on the safe side I always use a Credit Card rather than my Bank Account as the card supplier has a legal obligation to make right any problems. Most Credit Card suppliers now openly advertise their commitment to refunding for any on-line problems. They are liable wether they openly state so or don't.
