....on the remote, does it have buttons like the Empeg one ? (like artist, genre, source, year.)
No, it doesn't. Its software is significantly different than the empeg software. It is much simpler and more "dumbed down". Many of the advanced features of the empeg software (such as the tweak order feature you were just describing) are not present at all.
It does little more than let you select a parent list of songs by artist/genre/album and shuffle them. And it has playlists (albeit flat ones rather than heirarchical). That's about it.
