I really like the Latshaw Song List Generator. When you bring in lots of discs, it's inevitable that you have multiple versions of the same song (some gold standards like Sinatra or Elvis might have a dozen versions on different labels. Some singers like certain versions (Chartbuster, AllStar, Sound Choice) .. so the Song List Generator will pull those all together, assign a 2 letter code (alterable) to each brand and print out the song on one line, with the versions shown .. instead of a dozen lines showing the same title.
To each their own.
