How to Rename My iTunes Songs
It is easy to build a large collection of music on your computer, but it is not always easy to manage it. Take the time to keep up with your collection using the iTunes software, and name the song files so they can be easily found later.
Open the latest version of the iTunes software on your computer. Download the software update if requested to do so.
Click on the song you are wanting to change the title of.
Select "Get info."
Navigate to and press the "Info" tab.
Type the new title in the "Name" field.
Click "OK" to finish renaming the music title and save your work.
