Instagram is providing the feature of adding music to Instagram Stories. If you want to make your music available for the public in the app, you must distribute it to Facebook Rights Manager.
Instagram is linked to the Facebook Rights Manager catalog, from where the application gets the music that you can find available for sharing in their users' stories.
