Playing all music in the music folder

I am a long time SanDisk user. This on going problem should be fixed. Looks like a lot of people have a problem with audio books. In previous models you just change the tag of your book and it worked. Could we update this player with old software?? Sandisk this should be an easy fix to make a LOT of people Happy!

My first Sansa 250 powered by a AAA battery. Then I had a Fuse, best player ever, even watched videos on it. Then I got a clip, small light worked good for Three years. battery started going so I got the Clip sport. So I know my way around these players. I use mp3 tag to retag my books.
