There are a few ways to do this. One way is to use a third-party app like Move to Apple Music. Another way is to use iTunes. To use iTunes, you’ll need to have both an iPhone and a computer with iTunes installed. First, connect your iPhone to your computer. Then, open iTunes and select your iPhone in the Devices list on the left-hand side of the window. Next, select the Music tab in the main window.

On your computer, the songs are usually saved in the “Music” folder. If you’re using an iPhone or iPad, the songs are saved in the “iTunes Media” folder.
