How do I bulk rename albums in iTunes? I have an online subscription to a radio program that allows me to download past episodes. However when they are opened in iTunes the album name is set in the format Apr 01 2008. The problem is that there are thousands of these and I would like to change it to a better format such as 2008 01 Apr or even 2008 Apr 01. Is there any automatic way to change an mp3's metadata - or a program like a Better Finder Rename that can edit this iTunes metadata for the thousands of tracks that I have?
I recommend Doug's Applescripts for iTunes as a great resource to keep in mind for any future questions you might have. From it I found the script that applies sed to the track names. Once you follow the instructions to install the script, put the following code in the popup box:

s/\([:alpha:]\)+ \([:digit:]+\) \([:digit:]+\)/\3 \1 \2/ 


N.B. This is actually the first time I've used sed, so I recommend testing this out on a few individual songs first. 

(Also, if you don't have any programming experience, then it's likely that the Regular Expression above looked downright arcane. Don't worry! That's totally normal.)
