It depends on where you saved the music files.

Hi,

The library is the location in the Player that lists all of the music, videos, and pictures on your computer. It lets you easily find and play your digital media files, as well as choose content that you want to burn to a CD or sync to a portable music player.

To display your library, start the Player, and then click the Librarytab.
