Share Song (obsolete, see description)

This doesn’t work anymore, but an official Shortcut is available here which works. This shortcut sends a URL to Song.link and gets back a universal URL with links to other streaming services. You can send URLs for individual songs, and for entire albums. It doesn’t give the correct link if you try to link an artist page. This shortcut differs from the other similar ones in its speed, error handling, and testing. As of 1/05/2019 this is the best shortcut of its type. (I made it because the others all had limitations…)
