I am running windows 7, not Mac.
I do edit the tags so the Zip files the music consistently in a convenient location under composer/piece/track. There is nothing strange in them.
Some files play OK on the ZIP, some dont play at all. There is no obvious difference in the tag values between the two sets of files. I have copied a file which doesnt work on the Zip back to the PC - it is fine, the same as when copied to the Zip.
More info - the files which do not play do not show the Cover, the files which do play show the cover correctly, but again there is no obvious difference between the data associated with each file. To repeat my initial info, all files copied from Itunes have a corrupted Genre.
