You are making a perfect sense. My musical education is very limited. As an average late intermediate pianist i do know only some basic things.
Yes, there are only 13 notes, but the combinations are without limits.
I'm sure you are familiar with Beethoven's pathetique sonata, 1st mvt.
It opens with 2 simples chords. There are a hundrends of different chords available, and if we go into atonal music, there are no limits. Of course we can't say that someone is copying beethoven because he opens his piece with 2 chords. But if those 2 chords would be exactly the same as those in that sonata mvt, we could argue a lot.
As you said, YANA is very simple song, like most of stuff that r. pedophile wrote. But those 2 songs (first is actually a piece) are so incredibly similar, that the chances that YANA is plagiat are very high. We will never know the truth though...
But you are right when you are trying to say that most of the plagiats are simple songs. I have never heard that someone would plagiarise Pink Floyds or Beatles...
Again... Some "plagiat cases" are absurd... I read once that one band sued another band because they closed their song with the same scale. It was stupid of course, because scale is a scale and there is nothing new to invent when playing scale. But there are always suspicious cases like the one I posted when similarity is incredible.
