Share Apple Music Songs with Friends Using Spotify - Siri Shortcuts

Transfer the Song URL from Apple Music to Spotify to Clipboard and Share it.
I’ve turned on to show in share sheets, so just go play anything on Apple Music and tap the share icon (the three dots in a line), tap the shortcut it will transfer the song to a matched url for Spotify and copy it to your clipboard and open the normal share menu, just select the message app you’d like to use.
