How do I share a playlist?

To share a playlist you’ve created, simply go to ‘My Library,’ tap on the playlist you want to share, tap on the stack of three dots just below the playlist artwork and then select “Share a Copy” from the list of items that pops up. You’ll be provided a link, which you can then share with anyone you’d like. The receiver can make a copy of your playlist to add to their own library. If you update your playlist after sharing the link, the receiver will see the most updated version of your list when they open the link.  

The link does not expire, unless you delete the playlist.
