Podcasting Howto: the importance of (MP3) tags

Whole Wheat Radio says USE TAGS!

And he explains why and how.

Note that tagging is not just for MP3 files, MP4 / AAC files and other file formats support tagging as well.

A great free tagging application is: iTunes!

Just open the file in iTunes, go to 'File' -> 'Get Info' and then click on the 'Info' tab. The fields you fill out here are written directly to the tags and should show up in any other player.
