hey i got a problem, i use limewire to download mp3s, for some reason, some songs i can play in limewire but not in windows media player

its says "windows media player cannont play the file.the player might not support the file type or might not support the codec that was used to compress the file"

i use windows media player 10 and i have limewire version 4.8.1

if someone could help me out it would be much help,
thank you.
