Head to the Spotify Wrapped site and log in to your Spotify account. A PowerPoint-type slide show will tell you all you need to know.
Or head to the Spotify mobile app, go to “Search” and you’ll find the “Wrapped 2020” card, ready to go under “uniquely yours.”
If you want to add the playlist to your library, you can use the mobile browser or just access the Spotify Wrapped site from your desktop and save the playlist by clicking on the heart. Then, you can jump into your library on the Spotify app and it will be there, under playlists.
