I downloaded a live recorded song. Only when I tried to play it I noticed it was a .mp4. When I searched for the song I used the Audio search. I double clicked it and it opened in Winamp. I dragged and dropped into iTunes and it didn't work. I tried renaming the extension to .mp3 and .m4a. The .m4a went into iTunes but when I play it on my iPod, it plays the first few seconds of the song and shuts down the iPod.
Any help would be great.
