Gundam SEED Destiny OP theme

I'm officially confused. The raw of GSD 44 had a different OP theme than the Hiro fansubbed version. Is Hiro just being lazy, slapping the old theme in so they don't have to do karaoke for the new one? What gives?

I have GSD44 by Hiro and it still has the gay ass Chemistry song that it officially has, wtf are you guys talking about. I WISH they would actually change it since it's such a horrid piece ofs hit.
