iTunes will play all of your songs without repeats until you have heard them all as-is. A user would simply go to their music collection, select the shuffle action, and then begin playing a song. No song will be repeated until all of them have been played, which you should have been able to take away if you read the OP or the comment thread. As for the fact that your app is $5, I will refrain from saying anything besides do not spam the link to it on HN please.
