UPDATED: Playlist XML Librarian v2.0
I've suspected for years that there would come a time when I'd want one of my AppleScript dinguses to grow up into an Xcode app. You can only do so much with a single thread. I've been using Playlist XML Librarian pretty regularly and the AppleScript incarnation just wasn't able to gimme what I need.
Playlist XML Librarian v2.0 will list the exported Playlist XML files collected in a specified folder with options to view, edit and send (import) them to the Music app. Makes it easy to maintain an organized stockpile of exported Playlist XMLs to reduce the number of onboard Music playlists.
Also see Playlist XML Viewer which can display and play a single selected local Playlist XML file drag-and-dropped or chosen.

Latest version:
- Outgrew AppleScript, is now a full-fledged Xcode app
- Overall speed boost
- Checks each XML file for appearance in the Music app as status
- Sort playlist XML list by name, date, track count, playlist kind and status
- Additional Settings to configure status indexing and display
- Description overspill appears in popover
- Toggle playlist info visible
