I have some kind of old-school MP3 Player (Philips Go-Gear Ariaz) and it would be nice if you could add the possibility to sync music from your hard drive to your MP3 Player. You already have the possibility for IPods and Mobile Devices, so it should be easy to widen this for other MP3 Players too.
