I bought some songs from Itunes, but they wont show up anywhere but in Itunes. I can't open one up in my Window Movie Maker. but it's not just that it won't let me open it in anything. Itunes is the only place they play... there is a small lock in the upper left hand corner of the song file picture. Does this mean anything? any info would be greatly appreciated for I need to get this video done soon... thanks in advance.
