That is precisely the problem...

The whole case was "above their paygrade" so to speak.. They would have zero clue that the songs though both major arent in the same key or chords..

This ruling is very slippery since it is a copyright suit.. it's basically saying if you admit that a previous copyrighted work has influence and that you heard it.. you have to somehow clear the copyright for yours...

But then who clears copyright for these?
