Kirk lists ten things iTunes does right at Macworld.
I'm very partial to #10.
Make Mega Playlist will allow you to create a "mega" playlist built by appending the tracks of chosen playlists to it in their play order; the effect being that the contents of the mega playlist will play in "playlist" order.

I think I'll take the day off! Macworld reviews TrackSift as a Mac Gem and awards it four mice. Thanks!
Kirk McElhearn is Macworld's "iTunes Guy" and he recently chatted with Senior Editor Chris Breen in a Macworld Podcast. Subjects include a variety of iTunes issues and a couple of scripts Kirk uses in his regular iTunes workflow.
Macworld's Jason Snell describes in this article how to upgrade tracks with iTunes Match to 256kbps AACs. iTunes Match will allow you to re-download these types of files even if the matched tracks are lesser quality. To gather these lesser-quality matched-tracks together, Jason describes how to create a Smart Playlist with the correct criteria. I've created that Smart Playlist and exported it and have included it in a script which, when run, will add that Smart Playlist to your iTunes for you. Here is the direct download link. Just download and double-click the script; make sure iTunes is running. Be sure to read Jason's article to understand the rest of the details.
Chris Breen asked me to chat about iTunes and AppleScript for a bit on the latest Macworld Podcast.
And speaking of Macworld today, Kirk McElhearn has a nice article covering How to add lyrics to your iTunes tracks.
