The Likeness of music
I've wrote songs that sound like other songs from bands
I've never even heard, and probably say I think they suck too.
With only 12 notes in the western music system
music is going to be somewhat similar.
So it's really impossible to copyright a riff.
All music as everything should be public domain anyway.
Cause We all know the best artists "Steal" other peoples ideas anyway. That's why all pop music, "crappy music," sounds the same.
