Kinda strange? I am getting an error message on a few MP3's that will only play on WINAMP, yet won't play on Windows Media Player or iTunes. I understand the situation trying to play iTUNES on WINAMP or Media player. I get the following error message: "The file you are attempting to play has an extension that does not match the file format. Playing the file may result in unexpected behavior". I tried burning them onto a CD and NO dice......
