Brandon, I agree. but--that 21 G and BBM have this 'overlap' doesn't trouble me in the slightest.
Way long ago, traditional music had no authors and composers--just well-known themes that were borrowed without thought. Of course The Academy wasn't awarding Oscars for best score in those days, and people justifiably expect credit, compensation, acclaim.
Whatever happened, however it happened, it resulted in a miraculous pairing of music and images. I'm glad we have it. I think IT deserved the Oscar, regardless of WHO 'wrote' it, and if any one else genuinely deserves credit/money, I hope they get it.
I've got a fever, I'm raving, and I know it. Night all! See ya in the mornin' (I hope)--
