The Day Dave Died. Can someone suggest something?

Question:The day Dave died

Dave died today, a stain
Sour, lost and in vain
He was glued to his chain
It was clearly inhumane.
As a nerd, Dave remained mundane
He once tried to explain
That he had jumped on a moving train
He had said that it was so urbain
But clearly it was so inane
Much so that he was insane
More so that he was champagne
His mouth, a campaign.
The allure of the arcane
In Dave, sounded like pain
For Dave had a brain
Which was that of a constrain
Much though he did deign
That the world was of his reign
More though was Dave the bane
That was of the sane.
Dave liked to do cocaine
He said it was the main
Although he did not refrain
All he did was detain.
The falling rain
Showed it's disdain
At the funeral of that remain
I did though from the funeral abstain
Trying to obtain
A court ordered refrain
In case of the preordain
Of a macabre feign.

I have reread this three times. While you have some great thoughts and images liked "glued to his chain," the reptition of the same rhyme throughout the whole poem not only detracted but after awhile infringed because it became clear that many were forced. The main themes in this poem I see are addiction, inability to break away and relationship souring. To me I would take that great line "glued to his chain" and develop from there. Rhyme if you like, just mix it up more.

I have a feeling you listen to and/or enjoy a lot of rap music. This could be really good as a rap piece I think with all the repetitive same sounding rhymes.

I began to really get the message of the piece after about the 3rd reading so I can see this has taken a great deal of work and thought and purpose. Each line and word has been chosen meticulously and I applaud your work.
This style of rhyming doesn't work well as a poem because it's too repetitive but put to music, in rap style, this could be impressive.

You're good at using words but I don't know what you were trying to say. And I wouldn't want to, guess again. I'll leave it to the experts.
