I don't know if this is a bug of the new version or not, but what I notice is that extremely short songs don't seem to have their metadata changed. I'm running the latest version of iTunes on ML, and I have a Smart Playlist with one condition: play count is zero. Basically, after a song plays completely, it disappears. But not with two tracks - one which is 5 seconds long and the other 9 seconds. These two songs' play counts don't change to 1 (or however many times I played them). Other regular-length songs don't seem affected. Has anyone else run into this?
