LeechCraft

даже при беглом взгляде на сырые данные журнала воспроизведения, выявляются повторящиеся последовательности и закономерные шаблоны

STR:
Здесь описан метод сбора данных для статанализа.
1. создадим базу данных, в которую будем их собирать:

sqlite3 /tmp/tracks.db 'create table tlog (url,album,title,artist);'

2. Скрипт ведущий лог:

/tmp/tlog.sh
#! /bin/sh

sqlite3 /tmp/tracks.db "insert into tlog values (\"$1\",\"$2\",\"$3\",\"$4\");" 
qdbus org.mpris.MediaPlayer2.LMP /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next

4. настройки AN вызывающие логгер при смене трека:



5. выставляем режим воспроизведения очереди в случайное
6. загружаем плейлист
7. звук желательно отключить
8. жать play

Expected result:
Здесь должен был быть кусок статистики и теорвера, но не судьба.

Actual result:
На самом деле всё плохо, анализ данных можете провести сами, а в качестве примера вот:

% sqlite3 /tmp/tracks.db 'select count(*),url from tlog group by url having count(*) > 9;' | sort -rg
