A couple scripts for maintaining a directory of music files (probably located on a USB music player or SD card) from an iTunes playlist.

Requires the appscript gem.

###itunes-rsync.rb Query a given iTunes playlist, build a scratch directory symlinking all files of that playlist into it, then run rsync from the scratch directory to the path given.

Note: rsync's --delete option is used, so it will delete any files in the given path that are not found in the playlist.

Usage: ruby itunes-rsync.rb "ipod (auto)" /Volumes/music/iTunes/

###playlist_album_shuffle.rb Query a given iTunes playlist, organize all tracks into albums, shuffle the albums, and then print the filename of each track in each album (in its original track order) to STDOUT, relative to the path given.

Mimics the album shuffle functionality of iTunes and older iPods and can be used to create a few album-shuffled .pls playlists of a given list of tracks for players that don't natively support album shuffle.

Note: The path for the second argument is the path relative to all media as it would be mounted by the player. Nothing is saved to that path and the output is all done to STDOUT.

Usage: ruby playlist_album_shuffle.rb "ipod (auto)" /mnt/SD1/iTunes/ > /Volumes/AK100/album\ shuffle\ 1.pls
