If you are trying to play copy-protected songs, then VLC isn't the option for you. While it can work, it's not very reliable on copy-protected (itunes types songs, for example). Instead use the native application that you downloaded for those. VLC is for those who wish to play movies, music, cd's, etc, anything really, that you can normally play on a machine. If you are having issues playing a song, etc, you need to provide more details, or contact the VLC forums for answers. Your question was a bit vague, but i hope we answered it!
