Maybe I don't quite understand your problem, but I'm facing a problem with sorting folders. I found this Sorting for Luxury&Precision link here on forum and now it helps me to organize files on my P6.
Load all your music onto a program like foobar. Highlight them all, browse the metadata and delete all the extra metadata you dont need and just keep the bare minimum.
I kept track, album artist, album name track number.
If you want gapless, you can use cuesheet.
Thank you for the suggestions. I did not format it on the device. I am on a Mac and formatted it to Fat32 (MS-DOS). I first copied all my music onto the card and when I tried to update the media library it would crash/restart after a minute or so and whenever I would click on album or artist it would go into update media library again and crash.Did you format the SD-Card in the device itself? If not it might be a good thing to do it helped me with any freezes. Even if there is a freeze chances are that whole library is indeitified and you can use the the dap.
As already mentioned use drivesort software if you are on windows to organise the library on the dap, its basically 2 mouse clicks each time you album. By default it doesnt use the western alpha numeric system I believe.
I deleted all the music and added album in groups of 10, after group updating media library, which worked, until I cam to one set of album where it started crashing again. I found the album and when I deleted it, it was updating fine. I did not see anything obvious with the album. I got some software to retag the albums (MusicBrainz Picard), but I did not read / understand the instructions correctly and when it was done with my library it had deleted about 3/4 of my files.
Btw, whenever it was crashing the device when trying to update the media library, it would play music just fine from the folder view.
I had to leave for a trip and used the card from my AK player (formatted in ExFat) and it behaves the same way. Cannot update media library, but I can play the music through the folder view. Good enough for the trip, but I want to get that straightened out and maybe bring some order to my music library chaos.
Many thanks for the suggestions you gave me. I will try them.
Love love love the way the music sounds though. Sounds cliche, but with many songs it is like hearing them for the first time. So vivid, detailed and just sounding like I am there with the music. Amazing.
