The song Here comes the sum was conciderd for the gold record on Voyager 1. The Beatles were OK but EMI said no. Why did they say no?
Copyright doesn't apply in space. I'm not sure if that's the answer, and who in space would be stealing profit from EMI by using it, but companies do stupid things like that for stupid reasons, so I think that's it.
Except they allowed Across The Universe, so that probably just ruins my point.
