Hello I've got the droid RAZR and whenever I try to add new songs to a playlist they won't add to it, it shows a message saying __ number of songs added to playlist but they won't show on the playlist. I an using the my music app not the Google one and I've tried to hold on a song and click add to playlist but it won't work and I've tried to hit edit in the playlist menus then select new songs but they still won't add. There is no problem when creating a new playlist and so far that is the only way to add new songs to the list by creating a whole new playlist. Also all the songs are saved on the internal storage not the SD card.
