I tried four of the tracks again and they all stil got the crc error. I also tried the same four on my backup empeg and they failed on that player as well.

I then opened and saved each of the files in mp3trim (1.77a). After doing that, I was able to upload three of the four files. Btw, MP3trim did not report any errors on the original files.

This is the kind of results I've seen before, where changing the files works some of the time. Sometimes just deleting the tags has allowed me to upload.

Do you ever get these errors? Any suggestions on what to try next? Thanks in advance...
