Just the length. The artist/album/track name didn't change..

Although I''m not conviced about the length being the issue.

Only things that got moved this time have a problem. I moved all my J.K Rowling books a few weeks ago. It's also everything that was moved this time. All 571 files (my mistake earlier my error log had 4 extra lines of errors from rsync not readlink errors).

I've run chown/chmod on the mp3's and the symlinks that mp3tofids created (even though they were recreated). So something is just odd here
