If you're into Linux, and batch ripping/encoding/tagging is important to you, consider to use Jack

Hey, he stole my name.

(Jack was the name I used for a Fraunhofer/LAME front-end program I wrote a long time ago. Not very many features and isn't all that great, but at the time it was the only tagger/encoder front end that formatted the data the way I wanted it and used the Enter key properly to move to the next field.)
