If you right-click on a cart within the Media Finder you have two options for seeing the history of when that cart has been played, on the bottom of both windows you can specify the date range of what timeframe you would like to look between:
Audio History Graph
This will show you a graph on screen, this shows the hours in which the item itself has played (denoted by a Green block with an asterisk in) and also shows when that artist has played (denoted by a Yellow block with a hash in). Double Clicking on one of these blocks will take you to that item which has played.
Audio History Report
This will show you a list on screen, this shows the exact times of when the item itself has played. You can export this list by pressing the Print icon.
