What's a good program for ID3 tagging in linux? I obsessively name my MP3's according to the exact same format (which makes it very easy to avoid dupes in a collection of 3k+ songs, and allowed me to rip/encode my CDs at high quality and dump them over my existing collection to ensure I have the best quality of each of the songs). I would like a utility.. preferably command-line based, that can fill out ID3 tags based on my file names.. I'd plan on doing this to my whole collection, so I want something that will do rule-based batch processing.

thanks!
