According to the Jaikoz manual there is no way to edit these. I’m curious to know if a script exists to modify (copy and paste between songs) these tags.
I ask because Serato DJ uses these fields to populate program specific data. I am using iTunes Match to replace old songs and the new files, while maintaining many of the common tags, do not maintain this data.
A script that checksums both files (assuming they maintain the same filename) and writes this data would be ideal.
I’m raising the question in the Apple forums but if anyone has any ideas that would be great.
