Command line for adding mp3 meta data

[Robert Moskowitz]

I just purchased an audio download of 36 tracks.  No meta data, and my 
wife's flip phone needs meta data for sorting and such.

It is one thing to use VLC to fix the meta data on a single mp3 or 2 
before transfering to her phone, but 36 is just a road too far.

So is there a decent program with Fedora that will let me easily set the 
meta data on these?

thanks
