EDIT: got the "Blue Exorcist" one.

The release date for the "Re:CREATORS" rearrange CD was just in the last couple of days. I'm guessing it's taking longer because it was bundled with a blu-ray volume of the anime.

Thanks for any leads on it, on behalf of myself and a fellow Sawano-fangirl friend.

Got the "Blue Exorcist: Kyoto Saga" rearrange CD (thank you TheHeroOfMobius), but still looking for the "Re:CREATORS" rearrange.
