Despite the player's USB thumb-drive design you cannot simply drag
tracks to it from your hard drive, use Windows Media Player or any other
player you might favour. The only way to transfer tracks to the NW-E015
is to fire up SonicStage CP 4.3, wait for a while for it to boot up…then
wait for it to update information on the player…and then, when you try
to copy your music across to it, wait for it to update the track
information before finally getting around to performing the task at hand
