Q: i can't restore my recently added playlist to my iTunes

Howdy Tom,

Welcome to Apple Support Communities.

From what I gather, you would like to know how to restore the Recently Added Smart Playlist or re-create that Smart Playlist in iTunes on your Mac.

If you haven't already, you can try undoing the previous command by pressing Command-Z as described here:

If that doesn't resolve the issue, you can follow the instructions in turingtest2's User Tip for re-creating the Smart Playlists that came with iTunes.

Also, you can find a lot of great additional information about Smart Playlists in this article:

So long.
