I recently bought an mp3 player but found that a number of the podcasts that I listen to don't have their id3 tags written correctly or they sometimes change from show to show meaning that they jump around in the jukebox menu. I wrote this script so I could syncronise the tags on all the shows so they always appear in the same place.
The script comes with a few sample shows, to add more just create new entries in the show_details array at the top of the script.
To run the script you need the id3lib package installed and the ruby wrapper. I got the package from my distro package manager and installed the ruby wrapper through gem with:
gem install id3lib-ruby
