Perhaps it was not clear from Richard's post: emptool will read its commands from standard input, of course. So, instead of cut-and-pasting, just pipe your command script into emptool.

So perhaps something like this will do:
- Touch a timestamp file after each sync
- Obtain fresh 'ls -lR /' listing from emptool
- Use find to make a list of tunes newer than timestamp file
- Create upload script, using the player content listing to figure out necessary make list commands and to distinguish between new tunes and updated ones (which will have to be deleted from the player first)
- Finally, you could compare the whole player listing to that of your reference PC to find out which tunes and/or lists need just deleting from the player

Keep in mind that emptool will not report original tune filenames, but will use song titles instead.

(This is an example of superiority of command-line over visual tools .)

Good luck!
