Haven't messed with much tagging, but the way I'd approach it would be to insert a step that reads the tag and dumps it to a text file before converting to mp3. Convert to mp3. Then reapply the tag with some tagging app. Could probably be scripted with little effort.
Alright I found a good example. Google for oggasm. It's a PeRL script which recursively converts mp3 to ogg. It converts the tags and applies them to the new file as well. I'm just learning perl so it's a bit out of the realm of total understanding for me, but it certainly can be done...relatively easily it looks.
here's a short bash script that uses faad2 and lame to convert from .m4a to mp3, transfers all the tag information, and deletes the intermediary .wav and .txt files it created
the script still has to be saved and run in each directory containing .m4a files you want to convert, but I suspect that would be trivial to fix for anyone who actually knows a thing or two about bash scripts:
i tried all the scrips posted here and got the same error each time .......
"Warning: Pulse coding not allowed in short blocks" fills up the terminal
and then when it finally stops it says
Could not find "19 Track 19.wav".
rm: cannot remove `19 Track 19.wav': No such file or directory
go to the directory where your m4a files are and try running faad "filename.m4a"
on the command line
then do ls
if you don't see a ".wav" file then you have a problem. either you need to update your faad program or there is simply a problem with your m4a files. Also make sure you have the correct permissions. And that you are copying and pasting the scripts correctly and not just typing them in (sometimes that leads to typos).
If it is the case that your faad needs to be updated (and I see you are using fc3) then type yum update and finally yum install faad2
Hope that helps,
As for me I am using d-rockbrinks' script with much success and also learning a thing or two about bash scripting.
Thanks everyone who has contributed!

I used it to convert a DVDs worth of various artists.
Change to top level folder (e.g. itunes ;-) and execute 'convertr m4a2mp3' for example and the script will enter into all the subdirectories calling the conversion script specified.
THANK you whoever did it for making the ogg vorbis version, I don't want to use it, but shortly ago I spent several hours making and many, many more perfecting a script to convert mp3 to ogg. it hurts me deeply to find people ignoring this great format, and instead using inferior ones.
..I do realize that there is a better script written in perl that does it and with many more options but I don't really care and at the time I didn't know
