Now, William Hung can't sing either, but look what he did with what he had. He had a good attitude, most people loved him, and he got to be in the spotlight for a shortwhile. He was happy and he made others happy.
That's an excellent point, but it has nothing to do with singing. What you're describing is him being a good
performer, which I also disagree with, but I think the performance of him and "Chocolate rain" fall in the same self-deprecating popularity areas where the worse your performance is, the more popular you become. There's nothing wrong with it-- it's how Bush was elected, no?
I am speaking as a singer only. If she was asking people on her performance, then I'd say "droll". Doesn't mean I wouldn't be friends with her, or give her a MtGox T-Shirt care of Bruno. I'd just never ask her to sing at a show, and I wouldn't support her and lie to her if she asks for my opinion for example.
Let's cut to the chase, shall we? NaNa (hmmm!, as in Nakamoto) is currently a blank canvas. A blank canvas viewed by millions of viewers. Now, let's paint that canvas with a Bitcoin Magazine ad and have her sing "I Dreamed A Dream" from Les Miserables.
Images to get you inspired:

I wonder if NaNa planks.

Was just a blank canvas till Roger Ver paid for placement here. I'm sure he didn't just grab the first billboard that was available.

(prior, was a blank canvas viewed by millions of eyeballs) The Bloch Brothers Tobacco Company (also known as Helme Tobacco Company) of Wheeling, West Virginia, are best known for their Mail Pouch Tobacco.

Formally, a blank convas.

Now that's a Hot Spot! (double entendre intended)
