This folder is called OWN_SONGS.

Make new subfolder under OWN_SONGS. All files will be in this folder. And nothing else is needed.

Step 2:
Make audio file without vocals and name it 'comping.ogg'. It can be ogg,wav,mp3... as long as it's name is '.ogg'. If you want that selected language affects played file, name them with language-prefix, e.g: comping_fi.ogg will be played only if language is FInnish.
