Just taking a moment to express my appreciation of Automator on the Mac. I think there was a time way back when it seemed like an involved hassle to elevate an Applescript snippet into a Real Program(tm). Most likely it was just that I was too clueless to really search for resources that were already baked-in to the System Install CD's. But with Snow Leopard 10.6 [as of this writing, now 3 revisions, umm, obsolete. Heh], there is so much capability of Automator that I haven't explored.
For iTunes, I used Automator to package-up double-clickable Bash scripts that alter filenames and redirect using aliases. See [this] example for what I want to happen when I plug in a certain drive containing my music library. Disregard for a moment the way that I'm using condition checking in Bash...or even that I'm doing it in there at all, rather than in Applescript code. I'm just tickled to be able to prettify-ingly overwrap a Bash script this way. "Look ma, I created a real app on my Mac!", said the script kiddie proudly.
