what I'd like to do: find an efficient way of creating a more compressed copy of about 500cds worth of songs currently in mp3 at 320k. my dream would be to be able to point some compression software at the existing directory/subdirectories and have it create another set of files somewhere else compressed to 128 or 192. background: I've recently gone through a process of ripping all of my cds (about 500) using EAC + LAME. I used the highest available compression quality since I'm hoping to never have to take my actual cds out of storage again. But for my mp3 player it would be handy to have a set of all of these songs at a smaller/lower compression since I can't tell the quality difference on my mp3 player anyway and I could store a lot more songs. I've got several 200g drives so disk space is not an issue.
