Hey, I'm not sure if this has been addressed already, but here's something interesting I just noticed with my NW-A608: If I delete a song off of the device, and then send it again, there's 2 copies that are recognized in Winamp. After I unplug it, it doesn't detect anything in the database until I plug it back in and modify it somehow, so it forces a refresh of the database. Once I deleted a song off, it recognized there are 320/349 songs, for some reason. When I check the player, it recognizes duplicate copies of the songs I deleted and resent, as well. Again, sorry if this was covered already, but I don't recall seeing anything posted.
