Hey guys, need some help here. When I 'import a folder to library'into Itunes, there are songs that do not get imported and get left behind. (no message comes up or anything) And so then I tried to go to 'import file to library' and tried to import each file individualy. When I do that, on some of the files it says 'The above file name is invalid'. So when I change the name to something different, then it will work... but this is obserd as I would have to change like 1500 names of files on each song... what is going on???
