This application lets you add information to multiple songs at one time. For example, you can change the genre for several songs when you run the application.
First, you will be asked to select a playlist in iTunes. Next, you can enter information for all of the songs in the playlist. You can then add all of the songs to an existing playlist or create a new playlist for the songs. Note that you need to manually put a check in the box for the information you want to add or the application will not change the data in iTunes.
