I am not a programmer and know next to nothing about programming so if this sounds stupid, I'm sorry.

Is there a way that you can force people to logon to AM in order to request any songs and then once requested, the requested song will be grayed out to that user ID for say 14 days rendering it un-selectable for the 14 days by that user ID? On day 15 it will become active again. Kind of like spam guard that a lot of forums have but for a longer period of time.
