Workaround tip...
Use an intelligent list to sort by release date for 1 year, eg. 2019, then select all and add the YEAR - it will then be added to ALL selected songs:

Then you can use the YEAR criteria in the related playlists:

Has "Release Date" been considered for adding to search criteria when building custom Related Tracks? This was requested over 2 yrs ago. Is it a no go or on the list?
Release Date makes more sense than Date Added. People download throwbacks all the time. It would also allow us to build a more fine tuned "New Release" custom Related Track search.

Thanks for the response/feedback. Intelligent playlist does an outstanding job of utilizing the actual "Release Date" data. All of my tracks have excellent metadata, so the first step would not be needed. I currently use intelligent to capture New Releases by Genre and can customize the intervals, "Release Date, is in the last, ??? day(s)". I love this because it can be set and left alone/forgotten. The work around you suggest restricts me to a year and would require changing each year and/or depending on where you are in the year. PLEASE consider adding Release Date to related track searches in future update.
Thanks again for listening.
