I would agree that this was controversial show
and something that probably shouldn't be aired here often.
Personally, I didn't mind listening to it. While I'm not a metal fan in general and certainly not a fan of this particular style, I just took these pieces with a good dose of humour, and it seems that my state of mind wasn't hurt much, if at all.
It's ... hmm... refreshing to hear something different SOMETIMES, even if that something isn't "good" or "quality" music or so "pleasant" to listen to.
