Please, I don't know how to do this. Where can I add stamps to my new files? Can J use dirwatch to notice changes in my music directories?
You need the official playback statistics component available here
http://foobar2000.org/components/index.htmlWith this component installed every file in you library has %ADDED% field so you can write search queries such as
%ADDED% DURING LAST 14 DAYS
%ADDED% date is set when the file is added to the library (found on rescan, or dirwatch will probably do the same, haven't tried it)
