I want to share music from the Music app on my Instagram and Facebook stories so my friends and followers can link to it, how do I do that on iPhone?
While you used to have to use a third-party app to share your music on Instagram and Facebook, iOS 13.4.5 lets you share music to your Instagram and Facebook stories right from the Music app. On your iPhone or iPad running iOS 13.4.5 or later, open the Music app and play the song you want to share, then tap on the three dot menu button and tap Share.
Scroll to the right on the second row until you see Instagram / Facebook. Tap on the one you want to share with.
