Don't have to re-rip - just split them in Audacity. That allows you to label the individual tracks. Edit the metadata for the entire album (title, artist, genre, etc), add track titles and numbers as needed, and jRiver will look up the rest when you add the tracks to the library. That's how I ripped all my vinyl - full sides, then break down to tracks in Audacity. I clear the "recently imported" playlist before firing up jRiver after an Audacity session, and when the new stuff shows up, double check and tweak the tags if needed. Works nice.
