Convert iTunes Playlist to Rhythmbox

Solution: get perl script from http://dwelle.org/eg/transferratingsperl.zip - written by Bowen Dwelle (apparently).  YOU... need to test this if you place any importance on your Rhythmbox setup.  I... do not.  If wreck my playlists and/or library, I'm OK with resyncing the media and starting over.  I don't anticipate any issues/problems, but I did not write the script.

Situation: I have multiple machines at home, each with a different purpose.
MacBook Pro: Music, Pictures, Netflix, etc... Valve/Steam games
IBM T520:  Mostly work type stuff.
iTunes 10.6.3
rhythmbox-0.12.8-1.el6.x86_64

On the Mac I use iTunes to manage my music library, currently around 12,000 songs.  I think it is a very decent solution and meets all of my needs.  On my "PC", I run RHEL 6.3 and Rhythmbox.  (Rhythmbox is the only audio app I have managed to get working using RHEL with the standard repos.)

Issue:  Since my Lenovo is basically just a mirror of my Mac, I don't want to spend a ton of time managing the playlists on that machine, in addition to the Mac.  I was pleased to easily have found a solution that would rewrite the *.xml file for rhythmbox

Here are the EXACT steps, in a very repeatable procedure.
[jradtke@neo ~]$ rsync -urpolvv --size-only --delete morpheus-wlan:/Users/jradtke/Music/iTunes/iTunes\\\ Media/Music/ /home/jradtke/Music/

<!app procedure -- BEGIN
start Rhythmbox
Click Edit | Preferences
Select the Music tab, select "Watch my library for new files"
Let it sort through everything...
Quit Rhythmbox
!app procedure -- END>

[jradtke@neo Playlist-Conversion]$ rpm -qa | grep ^rhythmbox

rhythmbox-0.12.8-1.el6.x86_64

If you now start up Rhythmbox and look at "My Top Rated" playlist, you should see 446 files.

NOTES:

I will update this post if I discover any issues.  The one thing that impresses me is how well it works without modification.  In particular, the following:

on my Mac the path to my Music is the ridiculous path

/Users/jradtke/Music/iTunes/iTunes Media/Music

whereas, the path on my RHEL host is

/home/jradtke/Music
