please understand that our customer is located in all over the world, usually Chinese user don't care about any genre playback function , in fact, they are unhappy about we change the artist playback mode to Artist--> Album.
and the fact is most Chinese people download the music from internet but not purchase from iTune or Amazon online music shop, so the sound tracks usually does not includes any Tags and they used to play the music through folder playback.
Thanks for the reply James. I guess I will just arrange my songs in folders so that I don't have to rely on tags.
X5 is otherwise a fantastic player. Both the X3 and the X5 are the best DAPs I've used in each price range.
