The play list we used in Apple and Creative is defined as My Alblum for Samsung Media Studio. It is not as friendly as it seems when adding songs to the play list. You need to know some tricks to add songs to your album that you have created. The easiest method is to use Autoalbum to add songs to your playlist. It will automatic update songs to this playlist as long it contains the information that you have preset in the settings. The second method is to add the songs to Theme which act as a play list.  There are 5 preset themes for you to add your songs to the playlist. You just need to right click on the songs in My PC and select the theme you want. The third method is for album you created, you need to drag the songs from the My PC to the Theme you want on the My Album on the right hand side.
