To me, the Sandisk Sansa series works very well. Also, Philips GoGear has a folder view so it looks just like the folders in Windows Explorer. It will also arrange by artist and album and so forth - but if you have your files in a particular order in a folder, it will let you look at them just like that as well from the player itself. Sansa does not do this.

BTW, we bought the Philips in place of a Samsung - which I agree is wonky to use.
