To everyone who likes my music. nI have tried to add more songs but keep getting an invalid extension message. I have done all I can to fix it and get no results and no response from N1M. so I will have to find another site N1M is not refunding my money for my recent upgrade adn that is another issue with them. maybe they will wake up and offer a solution if not I will cancel and move on I just don't know where. thanks for listening to my music take care bye
