Syncing Music
In the Device view, a yellow star next to the Disc icon denotes a dynamic playlist. By pressing the Sync Music Keg button, any updates to those discs will automatically be copied to the DMS cartridge. If a disc has fresh content after syncing, the yellow star will turn blue and the new files will be highlighted. Be sure to click Save/Eject DMS to apply the changes.
