PLAYLIST EATING UP MY MEMORY in MEDIAMONKEY!!!

Ok, I just made my world changed.  I can create playlist now in MediaMonkey.

But I have another problem… :womansad: 

 

Does creating a playlists eats up memory??? My entire song list is only 556 MB, when I created several playlist… It doubles the memory, so I have  1112 total size eated up from my player.  :womanmad:

 

how can I suppose to retain the size of my entire song without being affected when I create a playlist?

Esp when using mediamonkey?

Please help!
