Songs

Why nowadays the most of popular nowadays English songs in English have a very small numbers of words very limited vocabulary? Should I be listening a to rap-songs or classic rock songs?

This is because the level of language education in the US has gone down drastically.  The newer generations have no patience to learn.  If you really want to learn from good lyrics.  Go back further back into the past few decades.  The lyrics are better and have greater imagery.  Take this 1953 example, "Stranger In Paradise".  The music is very haunting too.  http://www.youtube.com/watch?v=WVtp13FqHPU

Take my hand,
I'm a stranger in Paradise
All lost in a wonderland
A stranger in paradise
If I stand starry eyed,
That's a danger in Paradise
Mortals who stand beside
An angels like us

I saw her face
And I ascended
Out of the common place
Into the rarest
Somewhere in space
I hang suspended
Until I know
There's a chance that she cares

Won't you answer this fervent prayer?
Of a stranger in paradise
Don't send me in dark despair
From all that I hunger for
But open your angel's arms
To this strangers in paradise
And tell us that we need be
Strangers no more

I saw her face
And I ascended
Out of the common place
Into the rarest
Somewhere in space
I hang suspended
Until I know
There's a chance that she cares

Won't you answer this fervent prayer?
Of a stranger in paradise
Don't send me in dark despair
From all that I hunger for
But open your angel's arms
To this strangers in paradise
And tell us that we need be
Strangers no more
