What is the term given to an MP3 file that plays a song different from that of its file name?

Answer 1

wrongly labeled
mistake

Answer 2

mislabeled
mistagged
mistitled
P2P poisoning

are some ways of describing MP3s that don't play what they are labeled as, the last being an overall term for the intentional practice of polluting P2P networks with mislabeled files.

Answer 3

i dont believe that there is a term for that problem. I think it should just be called a fake or a mistake. If you want, just rename the file to match what it plays so as not to confuse yourself.
