Random function doesn't work how I want
 

Hi!
That's my problem:
I uploaded some songs with the media manager to my mp4 player. many songs are in different folders. Now I want to hear the songs at random. But the player only choose files that are in the same folder.

[Then I thought I create a playlist with all tracks but it doesn't work if I uploaded the tracks on an other pc, that's too time-consuming for me]

so is there another chance?
