Here is the link to the user manual if you need it; http://static.scribd.com/docs/wc5ee6ibupqr.pdf If you have the songs also on a PC (windows), right click on one of them and select "properties". select the "summary" tab, and select "advanced" if it is not already selected (shows "simple" if not). One of the properties listed is labelled "Protected" - if this is set to yes, then you need to have it set to no. The method of doing this will depend on where you got the song files from originally. If the protected tab is set to no, then there is an error in the settings of the samsung media studio program - select the help menu for more info (page 18 of the manual). Will the problem songs play fine on windows media player or similar? As a last resort, you could try resetting your mp3 player (page 66 of the manual), but this will lose you any songs on the player you do not have backed up elsewhere. back them up first. Hope this helps, please ask again if you need more info :)
