I gather the problem for you is being able to add all of your songs to the songbook plugin. You are able to successfully load the plugin?
Unfortunately the script for importing your songs into the plugin was designed to run under Windows, and I don't think it works on a Mac.
The script creates a file called SongbookData.plugindata. This is basically a text file containing information about the location and contents of your .abc files. You could create it manually, but it would be a huge PITA.
I think your only recourse is to copy all your .abc files to a Windows machine, run the script there, and then copy the SongbookSettings.plugindata file back to your Mac. If you want, you can zip up your "The Lord of the Rings Online/Music" folder and send it to me, and I'll create the .plugindata file for you. Unfortunately, this would have to be repeated whenever you add a new .abc file to your Music folder.
