I want to create a Smart Playlist (using whatev the latest version of iTunes is) for singles - that is, songs that I don't own the entire album for. Something like, albums with 4 or less songs (since I'll sometimes buy a couple singles but not the whole enchilada). This has got to be possible (doesn't it?), but my not-so-logical brain can't figure out the Smart logic. Do help! I've got a dental app't in an hour and would love to have this on my iPod before.
