A search of the forum yielded no results so I am posting anew.
It would be nice to be able to reset the Last-Played date/time from the Edit/Properties window.
MB v3.3.7261 on Windoz-10 with 137,063 song library.
I mostly use "SurprizeMe" smart-playlist where the criteria is simply: not played in the last four years.
If I get in a mood and play a whole album, I'll not be "surprized" with any of those songs for a long time.
I tried removing an album' (songs I'd played) from the library, downing MB, restarting MB and then adding the songs back; but MB remembered the last-played for the newly imported songs. Doh !
