I know I'm really late on this and if there's a topic about this case already, please give me the link. So I've been wondering if there's an official version of 'Dream High' with IU? Because when you listen to the song in this video: youtube.com/watch?v=zCJ7o7zJK_U&feature=related Starting from 1:00 min, I definitely can tell it's IU her voice, but if I search that song up, I only see the version with JOO. Could someone please help me with this? Pleaaaaseeee? I always wanted Dream High with IU, it actually would make much more sense. I hope you could understand everything, since my english isn't really good.
