How do you instruct Sonic Stage v 4.3 to refresh your MD or MP3 player with new, least played or least transferred songs? It also seems that Sonic Stage will not delete or replace the songs on the player; you have to first delete them manually before transferring. It looks like it might be the dynamic playlist function, however it's not clear whether Sonic Stage can monitor the number of times you play a song on the MD or MP3 player or just the number of times you play the song on the computer. I'm guessing it's the Dynamic Playlist function, but I do not have it working properly.
