The other day I added a bunch more music (mp3 tracks) on my USB, but some of it is showing up in what I can only say is random order on my infotainment display. That is, when browsing by "Folder," the album folders are not listed alphabetically, and even within a folder some of the tracks aren't listed numerically either. For example, I have a few multi-disc box sets that I ripped, all nested in an album folder, but when I select that folder it lists the folders for the individual discs as "6,1,2,3,4,5." There seems to be some correlation in displaying the folders by the times I added them to the USB drive. For instance, the music I added a few weeks ago shows up earlier in the folder list than the ones I just added the other day (most but not all). Is they some better way of sorting the music on the USB drive either via the info unit or by structuring the files on the USB drive itself? Am I doing something wrong?
