First, close the VirtualDJ LE software.

Make sure that the iTunes option to share the iTunes library XML with other applications is enabled. To do so:

  • Open iTunes, go to Edit > Preferences (in macOS: iTunes -> Edit).

  • Go to the Advanced tab.

  • Make sure that the Share iTunes Library XML with other applications option is selected (i.e. ticked).
  • Restart the DJ software.
  • If your iTunes library is still not visible in the DJ software, reinstall the DJ software.
