I think some examples might be appropriate here to help illustrate your points. If the music itself is bad, there's not really a way to quote it on the site, but you can always back up your lyrical analysis with some evidence!

indeed, but pithy nonetheless - thanks and welcome John!

I submit for your consideration, the following lines from the song 'My Aphrodesiac is You':

Alright, I could sniff some powdered rhino horn,
And go to bed in rubber gloves.
But I don't need no stimulation,
Potions, balms or embrocation,
I'm in love,
In other words:

Don't smoke no grass,
Or opium from old Hong Kong,
That hubble-bubble
Just makes me see you double
All night long.
Don't waste my time
With Spanish fly and roots to chew,
They cause me trouble,
Because my aphrodisiac is you.

a failing of blasphemous proportions for such a reputedly "international" artist

ok.

"So I stop one day to figure it out,
I'll quit my job without a shadow of a doubt,
To sing the blues that I know about,
My life is just a slow train crawling up a hill. "

and...

"This is the closest thing to crazy I have ever been
Feeling twenty-two, acting seventeen,
This is the nearest thing to crazy I have ever known, "

and...

All the lyrics to 'My Aphrodisiac is You'

and...what is this writing?

"When that man and I are wed
I'm gonna keep him warm in bed
And when my man's no longer hot
I'm gonna bring him a vodka shot
And when that spirit's made him strong
I'm gonna stay with him all night long
I'll be holding on tightly
Woah, woah"

and...

"You are the tiger burning bright
Deep in the forest of my night
You are the one who keeps me strong in this world."

I'm not bashing her voice, its not that. But she starts these songs, gets the listener in a certain 'mood', and then sings a line as if your parents are turning on the lights as you are making out on the couch with your girlfriend. Mood interrupted, not going back.

I'd say that was ample specification!
