Hi, I'm using a 64gb NWZ-A17 walkman with 128gb SD card and MediaGo 3.0.

Is there really no way of creating and editing a playlist directly on the walkman using the music files that are already there? I'm finding I have to create it in my library first and drag it onto the walkman before the playlist will show up on the walkman itself. I have to actually delete the music from the walkman first before making a change to the playlist, and that's certainly not very convenient. With iTunes/iPod, you can drag and drop on the device itself. Is that not an option with Sony? 

Thanks for any help,
