Instagram is a great platform for sharing photos and videos with friends and family. But what if you want to add music to your posts? There are a few ways to do this, but the best way is probably through the app’s Music app. First, open the Music app and sign in. Then, click on the three lines in the top left corner of the main screen and select “Add music” from the list. Once you have added music, it will be available in your posts as well as in your library. To play it, just hit play or pause on your phone or computer.
