itunes, you have failed me

so according to the genius thing that helps you make playlists n*sync's Bye Bye Bye and Dirty Pop, along with Larger Than Life by the Backstreet Boys belongs on the same playlist as All the Right Moves by One Republic. because of this lasp in judgement by itunes i decided to hit the "refresh" button thinking it would give me a brand new playlist and hopefully with some of my better songs included but instead it shuffles the songs around, isn't that what the "shuffle" button is for?
