If you’re like most people, you probably have a few greyed out songs on your iPhone. These are songs that have been removed from your music library but remain in the “in use” category. To delete these songs, you’ll need to find their album art and tap on it. Then, you’ll need to select the “delete” option and confirm your deletion by pressing the “x” button. Once you’ve deleted the greyed out songs from your iPhone, they’ll be gone for good!
