Import from iTunes File Sharing
iTunes file sharing is a way to move files on and off of your device using a computer running iTunes and a USB charging/syncing cable. Once files are added to OnSong using iTunes file sharing, you can import those files in this screen.
The first step in this process is to add files onto your device using iTunes file sharing. This is done using the iTunes application running on a Mac or PC.
You can browse the contents of your iTunes file sharing location using the import menu. Tap on songs to place a checkmark next to the song to mark it for import. Tap again to remove the checkmark. You can also tap on the Select All or Deselect All buttons at the bottom to select or deselect all of the files in the folder.
Once you have some files checked, tap on the Import button in the upper right corner to begin the import process. If you have selected to import a file that was already imported, OnSong will have you choose an action to take on the duplicate file. When the import process is completed, you are returned to All Songs screen.
You can delete files from iTunes File Sharing by swiping right to left over the name of the file. This will reveal a Delete button that you can press to permanently delete the file.
