I am amused by the idea of a crackhead, straining to figure out how to be indulgent and decadent, and only coming up with the idea of listening to two kinds of music at once.
A friend of mine, working on a science-fiction space-opera kind of story, was trying to come up with a pleasure planet for rich aliens and... all he could kind of come up with was a planet of alien sex and casinos and drinks with alien names and so on.
Myself and another friend then proceeded to come up with some ACTUALLY decadent science-fiction ideas and by the end, we could tell that his mind had never gone into the dark places that our minds went with it.
But, then again, he was probably the better for it.
We came up with a place where they collect the last specimen of an endangered species so that a rich person can pay a large amount of money so that they can kill it, we came up with a rich alien who gets high by mainlining hot needles filled with childrens' tears.
We came up with the idea of a place where you can go, select a person out of a crowd of unsuspecting folks, have them kidnapped, put through a forcible sex change and then awaken to your taking their new virginity.
It was endearing, kinda, that all he could come up with was... y'know... a hooker with four tits.
It is endearing that the strung-out squirrel can only come up with double music.
Also, the Flaming Lips album "Zaireeka" is actually quadruple music.
