I have 6000+ songs on USB which I play most of the time when driving. Because there is no support for playlists I first tried to create lists by genre and re tagged all my songs so I could fake playlists. This did not work as the Media player used Gracenote genre and not mine. As FLAC can have several types of tags I even changed the formats of the tags to see if any were used. No luck. My next solution was to use two USB drives and breakage music into two big playlists. Then I would select the USB drive and select songs and having shuffle selected I would get a random selection across all the music on one of the drives. This also solved the problem with phantom music playing when the car was charging. With shuffle on, the car never reached the end and get stuck on the last song in a selection. Now with 8.0 two changes to this have wrecked this process. First the shuffle option turns off regularly so I have to keep, turning it back on. This I could fix by adding an extra step each time started playing music. The bigger issue is that now it plays the same songs in the same order each time. I have listened many times since 8.0 and I now can predict the next "random" song. I have even tried starting with different song but it still does not play different songs. I never noticed this before. Shuffle may not have been totally random but at least I got different music each time.
