here are some of the ones i know, some a bit.. um.. abstruse (i.e. 'in my own mind'):

the beatles - happiness is a warm gun
"when i hold you in my arms
and i feel my finger on your trigger,
i know nobody can do me no harm
because happiness is a warm gun."

bruce springsteen - secret garden
"she'll let you in her house,
if you come knocking late at night.
she'll let you in her mouth,
if the words you say are right.
if you pay the price,
she'll let you deep inside.
there's a secret garden she hides."

the doors - light my fire
"the time to hesitate is through
no time to wallow in the mire.
try now we can only lose,
and our love become a funeral pyre.
come on baby light my fire..."

johnny cash - ring of fire
"i fell into a burning ring of fire.
i went down, down, down,
and the flames went higher.
and it burns, burns, burns
the ring of fire, the ring of fire."

the magnetic fields - lets pretend we're bunny rabbits (ok, so they're not all so abstruse..)
"let's pretend we're bunny rabbits.
let's do it all day long.
rapidly becoming rabid,
singing little rabbit songs.
i can keep it up all night;
i can keep it up all day.
let's pretend we're bunny rabbits
until we pass away."

talking heads - sugar on my tongue
"she's my neighbor. fill my cup.
i'll bet you baby, she can fill it up.
she'll put the sugar on my tongue.
will she gimme gimme gimme some?"

ween - let me lick your pussy (i said they weren't all so abstruse, didn't i??)
"let me lick your pussy, let me lick your cunt
let me eat your body, baby, let me make you squeal and grunt
let me show you how to please me baby
let me show you how to tease me baby
baby baby babe get down on your knees"

i feel like posting some rap lyrics.. but maybe that'd be a little too non-abstruse (can anybody say akinyele?)
