That's because music now is boring and uncreative, and all of the lyrics are incredibly generic. Go and read even popular music lyrics from the 80s or 90s and compare them to what's out now, and the difference is astounding. Like that song "W.A.P." was controversial, but the controversy covered for the fact that it had incredibly simple and dull lyrics:

Whores in this house

There's some whores in this house

There's some whores in this house

There's some whores in this house (hol' up)

I said certified freak, seven days a week

Wet ass pussy, make that pullout game weak, woo! (Ah)

Yeah, yeah, yeah, yeah

Yeah, you fucking with some wet ass pussy

Bring a bucket and a mop for this wet ass pussy

Give me everything you got for this wet ass pussy

Beat it up, n\**a, catch a charge*

Extra large and extra hard

Put this pussy right in yo' face

Swipe your nose like a credit card

Hop on top, I want a ride

I do a kegel while it's inside

Spit in my mouth, look at my eyes

This pussy is wet, come take a dive

There's nothing to it; the only vaguely amusing line is "swipe your nose like a credit card." Compare that to:

Dark in the city, night is a wire

Steam in the subway, earth is afire

Do do do do do do do dodo dododo dodo

Woman, you want me, give me a sign

And catch my breathing even closer behind

Do do do do do do do dodo dododo dodo

In touch with the ground

I'm on the hunt, I'm after you

Smell like I sound, I'm lost in a crowd

And I'm hungry like the wolf

Straddle the line in discord and rhyme

I'm on the hunt, I'm after you

Mouth is alive with juices like wine

And I'm hungry like the wolf

"Hungry Like the Wolf," a top 40s hit, obviously has far more complex and interesting lyrics. "Straddle the line in discord and rhyme" is far more interesting than "Bring a bucket and a mop for this wet ass pussy."
