I recently bought a 2014 S. Looks like the player does not list MP3 music on a USB by artist or song name. I've ordered the files and am pleased to see that it plays them in the order I chose. But the music is listed (shows) by filename. Not clear that there is a way to see them sorted alphabetically by name or grouped by artist. The iPod button does not produce a response. I'm assuming this player just doesn't have these capabilities.
