Remember that iTunes Playlist Algebra feature idea I talked about not six weeks ago? Well the new version of iTunes (4.5) has it. It would be nice to think I had a hand in it, but I seriously doubt it. :)

So that's pretty cool. I have my static playlist called "albums" that I manually add albums to. Then I have another smart playlist (which is dynamic) called "singles". The singles playlist rule says "give me all of the songs that aren't in the albums playlist".

That's all of my singles, my friends! So now I can manage all of those stray singles. Awesome. I also found a few albums that weren't in the album playlist and should have been. Now I just have to figure out one thing:

Library size: 792 songs
albums playlist size: 590 songs
singles playlist size: 205 songs

Pretty strange eh? I must have three duplicates in the album playlist somewhere. OK, next request: allow a setting so a given playlist cannot have duplicate songs. :)
