+This is an alist of items (AGE . FORMAT). AGE can be a number (of
+seconds) or a Lisp expression evaluating to a number. When the age of
+the track is less than this number, then use `format-time-string'
+with the corresponding FORMAT for displaying the date of the track.
+If AGE is not a number or a Lisp expression evaluating to a
+non-number, then the corresponding FORMAT is used as a default value.
+
+Note that the list is processed from the beginning, so it should be
+sorted by ascending AGE. Also note that items following the first
+non-number AGE will be ignored.
+
+You can use the functions `emms-last-played-seconds-today',
+`emms-last-played-seconds-month' and
+`emms-last-played-seconds-year' in the AGE spec. They return the
+number of seconds passed since the start of today, of this month,
+of this year, respectively.")
