Doh!

In a fit of stupidity, I managed to delete all the playlists that I have created over the last several years I've been DJing.

And by "delete", I don't mean they're sitting in the recycle bin...they're gone, gone, gone.

I meant to just clean up space.

And something went wrong while I was cleaning, so I wanted iTunes to resynchronize itself. So I deleted the files I thought would force that to happen.

Well, it does need to resynchronize.

Because it's entire library database is GONE.

So are all its library database backups.

Doh.

On the bright side, I found a disc backup I made in June 2006.

On the dim side, that's still nearly a year and a half of playlists that I'll never get back again. Including every event I've ever DJed with Ravenna.

Bugger.
