Indeed it's more than music, its art. For Example lets take some rap lyrics:
from freedom wrote pages unlimit, now my rage is infinite
so i'm finishing the timid with the stands of my mimic
better believe it, 'cuz I am the titan with a granit right hand
that embedded in led invented light, man
so the discovery was ready, son, fuck Edison.
ANd lets take some inna lyrics,
Feel the music nanana lalala nanan lalalla
THis verse is half of the song
So lets make the conclusion: you dont need to judge much to understand the " nananna lalalal" lyrics, right?
One more proof is, when Mixmaster read the rap lyrics had no idea what's there.
