i'm listening to my iPod, and then I think "Oh, I should put this song on that mix I'm making for so-and-so" or "this track sounds distorted, I should re-rip this CD." How do I capture that? I've reserved the one-star rating to denote ACTION (using ratings 2-5 for their customary use), so I tag the song with a one-star rating on the fly. Then I have a smart playlist on my home machine that only includes one-star songs, called, unsurprisingly, @ACTION.
