The date is a very important characteristic of a recording (in particular for merging, but also for more information about the release including this recording, etc.).
For the moment many recordings have a date which is present in the ARs ("Recording-Work", "Recording - Artist"). But this date is shown only in the pages which display the ARs ("Recording", "Work"). It would be very useful to show the date also in other pages which show a list of recordings: "Release", "Recordings (of artist)", "Search Results (for recordings)", etc.
