I have a 2016 and wish it played by folder, but it does not. I changed the name of the album on each song to the folder name to get around this. Some of my folder names were Country, Pop, etc. In some cases I could have done the same thing by changing the gene to the same folder name and got the same result. Don't have a reason as to why they went away from playing by folder. Maybe in the next iteration it will be back.
