I dont know if this is true. For example sine waves, saws and square waves are very intuitive to me. I think with graphical representation of sound the problem is that the experience of complex sounds is a 3 dimensional thing to humans.

When we talk about music, layers or tracks or whatever you want to call them always become a thing.

For the sound nerds: A spectrum representation also does not reflect how we experience sound. We humans/animals are so trained or born to distinguish sound sources by timbre. A spectrum analyser splits it on the spectrum of tones, not the spectrum of timbres, therefor it's still not a good representation.
