Huh, I thought to recognized you from somewhere.
Yeah, OCR's known for being extremely particular about what they "approve of" and what they don't. It used to be a lot more lax, so I'm told, but I guess after VGMix launched, OCR decided they wanted to be the "higher quality" remix center on the web. Now VGMix is pretty much dead, and the rest of us are left to figure it out for ourselves without the benefit of having a thorough practice 'n critique center that VGMix was known for. It was the grade school to OCR's college-level. That's why I never could get past making crappy sub-part remixes. (and I couldn't afford high-quality equipment or the time tore-learn music theory)
Anywhoozle.....
I can't contribute music, but if you actually do make this into a collaboration that meets the OCR strictness, I can do album art for you.
