My husband synched his ipod to his PC and lost 3000 songs, none of which were illegally downloaded. They were copied from CD's which he purchased. Appears they are in a file called MPeg 4 Audio file which cannot be accessed on his PC. Could anyone help with retrieving this music please? None of the songs purchased from itunes were deleted! Thanks After methodically checking and trying allsorts there is a way of retrieving the music albeit painfully slow. Access MPEG4 click on each title and send it to iTunes. If anyone knows of a faster way, please let me know. Thanks.
