[quote author=“Ishii”]Unfortunately, you can’t utilize the drag-and-drop concept for mp3s. After all, this is Sony we are talking about. But it is really not that bad.
That’s true and FWIW, you can’t simply drag-and-drop files onto iPods either and play them.
While in concept it sounds like it should be a no-brainer idea, it does make some sense especially with larger storage media players. Since you have so much data on the device, you’ll want to be able to find songs quickly and having the data pre-indexed by the transfer software allows the device to find songs quickly (thus using less battery power). That said, on some Sony MP3/ATRAC3 players, you get VAIO Music Transfer (aka Music Move) which is a little applet that lets you drag and drop music onto a device (it re-indexes the files in the background).
