How would I go about finding the bitrate of a given mp3. In other words; if I was at the command line and wanted to run a script that will list all my mp3s and their respective bitrates..how would I go about looking up the bitrate info?

nm, I found what I was looking for. I am just using already made libraries ;d If anyone wants to go into detail about how to get what I was looking for, feel free to explain, it won't goto waste (I wouldn't mind hearin it ;))
