The 2010 es350 can play music directly from a usb stick. However, the content format rules are unclear. I started out with all the song files in a single folder called music and discovered only 250 of the files were recognized. So I figured the content format must expect something like album folders or artist folders. Alrighty then, I reconfigured the usb stick to contain music organized by artist folders. Presently there about 100 artist folders containing around 1000 song files. This approach seems to work fine. But much to my surprise the folders are not listed in alphabetical order. They seemed to be listed somewhat randomly. So I figured maybe the date is used as well as the folder title to sort the list. Sure enough, after changing all the folders and files to the same date and time the folders were sorted as expected, except for a couple of folders. The two exceptions are a complete mystery to me. Anyway, none of this is explained anywhere as near as I can tell so perhaps someone else has some wisdom they can bring forward on this subject.
