I'd give them some talent points if they weren't using any vocoder-based software like Auto-Tune. That stuff is just plain annoying. It was annoying when Cher did it in the late 90's and it's still annoying today.
Well, I disagree with you in this case. I don't listen to music with auto-tune like this, but to use it for this purpose I think is perfect.
Cher and the like use it to affect their singing voice. These guys are using it to turn people who aren't singing into people who are. I don't see any other way they could do it, so it's fine with me. Plus, they tend to sing their own parts without the vocoder, and they actually have decent voices (as you can tell from the end of the Double Rainbow Song).
At least someone in the younger generation is watching the news!
Yeah, it sounds like they watch an unhealthy amount of C-SPAN.
