Anytime she performs on The One Show or The Voice etc you always get knobheads on Twitter saying it. Saying that though these are the same twats that claim she mimes...
If Kylie's voice just isn't your thing then that's fine, you can say that.
I don't like a singer = they can't sing is right out of the boomer handbook, and is almost never, if ever, applied to male vocals. TV shows like The One Show are hardly the best place to showcase your vocal and their audio team will always mix your vocal louder than the backing track which never does anyone any favours, wether it's a live band or a backing track. I also feel like the "they can't sing" thing has also increased intensity since multitude of TV singing competitions reinforced the belief that the only worthwhile female vocal was a Whitney Houston vocal.
I really wish Kylie had been booked to blast out that operatic outro to "Your Disco Needs You" on
The X Factor in its prime. She'd still get the same comments, but boy, what a moment that coulda been back then.
