Sure, I can guide you through the process of recovering lost playlists on Spotify. Here are the steps:

1. Log in to your Spotify account on a web browser.
2. Click on your profile in the top right corner, then select "Account" from the dropdown menu.
3. In the left-hand menu, click on "Recover playlists".
4. You will see a list of your deleted playlists. Find the one you want to recover and click "Restore".
5. Open your Spotify app. The recovered playlist should be in your library.

Remember, Spotify keeps your deleted playlists for a while, but not forever, so it's always a good idea to recover as soon as you realize a playlist is missing.
