I've found a bug in omp
Sometimes I get lots of blank "album slots"
It'd be about 4 pages or more
Reproducibility is veeery low (1/25) so I couldn't make a log.
But I'll post the screenshots soon

EDIT: about the shuffle order: I've got a proposal of additional algorithms. They could be set in settings.

1. Code:

   Miliseconds % number_of_songs

2. (To be set by the guy which are used):
   Code:

   (day + month + year + hour + minutes + seconds + miliseconds) % song_number

% - modulo
