Sure, I can guide you through the process of recovering lost playlists on both Spotify and Apple Music.

For Spotify:

1. Log in to your account on Spotify's website.
2. Click on 'Recover playlists' in the menu on the left side.
3. Find the playlist you want to recover and click 'Restore'.

For Apple Music:

Unfortunately, Apple Music doesn't have a built-in feature to recover deleted playlists. However, if you have a backup of your device, you can restore it to recover your playlist.

1. Connect your device to your computer.
2. Open iTunes and select your device.
3. Click 'Restore Backup'.
4. Choose the backup that contains the playlist you want to recover.

Please remember to back up your current data before restoring an old backup, as this will replace the data currently on your device.
