I have a smart playlist that, in addition to excluding some genres, requires a four our five star song rating. Cool. This morning, while walking the dog, I heard a song I couldn't place. I got home and realized the following: If an album rating is set, but a rating is not set for a particular song, iTunes gives the same rating as the album to the song, in those little hollow stars. What I didn't realize is that smart playlists apparently treat the hollow stars/"guessed" rating the same as a rating I've actually set. So if I buy an album and give it 4 stars, but only rate a couple singles that I already love, the rest of the songs get dumped into my playlist, even though I haven't rated them, specifically. So what's the deal? I know, I know, "rate every single song" is the obvious answer. And I will work towards that. But in the meantime, how do I get playlists to pick up only songs I actually rated?
