When i start a "shuffle all" play from library, this is the process:
-Play all shuffle from library.
-Open the Now playing view.
-The first song played display "1/1" (yellow at the right of the screen).
-I push the "next" button.
-The number is now "2/34".
-I press again "next": the total number of tracks increase quicly, it is now about 2000.(I have 5000 tracks).
It seems the display of the total number of tracks isn't refreshed quickly, so to viex it, i have to make a action:pressing a button, or even turn off/on the screen.
My 5000 tracks take about 3 min to be displayed as the total number of tracks: It is not a problem..
But now, if i add tracks from a folder external from library:
-Long press of my root music folder (folder not include in library).This folder contain 25 subfolders and these subfolders contains about 350 tracks.
-Press the "play" button.
-The "shuffle" button is enabled on the now playing screen.
-The total number of tracks is "2" at the begining.
-I force the display to refresh by turning it off then on.
-After about 2 minutes, the total of tracks added is only 90.
So the process of adding tracks to the now playing playlist is a lot longer with out of library tracks.
What's the problem ?
Because the tracks are always added in the same order, each time i start a shuffle playing of a selected folder, it is the same track which is played, and because the others tracks are long to be added to the now playing playlist, if i press "next" to listen to a another track, i have another track played but from the same album
So the solution is to wait about 1 minute if i want to listen to an another album when i press the "next" button.
A solution could be to add the tracks to now playing playlist shuffly, and not only play it shuffly.
It could be did by a new button "play folder shuffly", but i don't know if it can made.
Another solution maybe could be a faster microsd card and card slot...
Thanks
