Set the Plays ("Play Count" before iTunes v9.2) of the selected tracks to a user-entered number (they will all be set to the same number). If this number is 0 then the Last Played date of each track will be erased. (iTunes has the ability to "Reset" Plays to 0 from a track's Info window.)
iCloud Music Library users should beware of a potential bug.
