In latest build, 9427, there are two new fields: Last Played and Total Play Time. Both are available for displaying in a table view or printing.

To find out what are the most played albums, you'll need to add column for Total Play Time, sort by that column, and look at the top of the list.

Initially both fields are empty, so you actually need to play CD albums using OrangeCD Player first to collect some statistics.
