Yet in theory, a company could pitch a fit about its IP being used without their consent in some oddball way, and demand that all remixes of its music be taken down. After all, Square-Enix has made a C&D name for itself going after free works that are based off of their IPs, as have other companies (Blizzard, Nintendo I believe, etc.). So while OCR might not get shut down, there is a chance (albeit a slim one) that some of its content could be gone if a company pitched a big enough hissy fit with its lawyers.
