How do I copy the location of a track to the "Comments" section in iTunes?
Because you copy the location to the Comments variable.

Here's how to put the location in the comment tag.


tell application "iTunes"
  tell track 1 of playlist "Test" to set comment to (its location as text)
  -- or set comment  of track 1 of playlist "Test" to (get location of track 1 of playlist "Test") as text
end tell
