What is "Recently Added" criteria?

A couple of days ago 3 albums were put into the “Recently Added” category and i don’t know why…

All 3 albums were on my NAS, released in 2013 and had not been played recently. Time stamps were all 2013. Checking whether I could delete them, it says they are local (on the NAS).

A newly downloaded Aqualung HDTracks album added yesterday appears as it should.

Thanks for any help, I want to remove these albums from this category.

I was wondering the same. When I add my music directory to Roon, All of the albums are marked as “new”.

When I fixed up a corrupt track on three albums, the albums were then listed as new.

IMO, fixes should not move an album to “the front of the line”, only the addition of new albums, not already in library.
