Make sure that the your project folder isn't in a location that is protected by Windows (ie. in either of the "Program Files" folder) or in a location that is manipulated by third party software (ie. Dropbox has been seen to cause problems like this). Also make sure the project folder isn't marked with a hidden property, this could cause this type of issue.
It seems the issue was the title of the song and/or the artist was too long.
