They should match, but Played# can be manually edited. If you see this happening on 2024.1 (ie. a song without Played# and without Last Played) then shows Last Played without Played# then we can troubleshoot. Otherwise the question would be when and what past build could this have happened with.

I have songs in my library which have a Played count of 0 (empty), but do have a Last Played date. Is this a bug, or do these parameters work in a specific way which I'm not aware of? Thanks
