If you’re like most people, you probably have a few songs on your iPhone that you want to keep track of but don’t want to sync them with your music library. If you have an iPhone 6 or newer, there’s a way to add songs without syncing them. To add songs without syncing, first open the Music app and select the song you want to add. Then tap on the three lines in the top left corner of the screen and select “Add to Library.” The song will be added to your library and can be accessed from any device that has an iPhone.
