I have entered tag information for 1000 songs. I wish to copy the tag information in the column 'year' into the column 'track' so as both columns read exactly the same. How do I do this in bulk? There seems to be no feature to copy tag to tag.
You can use a 'Format value' action. Either through 'Actions (Quick)' or create a saved action group containing a single action:
Action type: Format value
Format string: %year%
Or, you can use the Tag to Tag converter using the same field and format string.
