who is the best and the worst singer on stage......miley cyrus,demi lovato,selenagomez

I think that they all make the same music, which is pretty overrated.
But that's just an opinion.

All of their Muzik is basically the same, but I think Demi has the strongest vocals without autotune so she's probably the best live and Selena Gomez can't sing for shit so she's the worst.

Demi has very strong vocals. Miley has a sassy voice, i like it. Selena has high-pitched voice, she can't sing well. So i'll say demi has the best voice

They all suck and their Muzik isn't good at all, soon they'll be forgotten because there are a ton of new artists who have been coming out with new Muzik lately and people will become lebih interested in them.

Well I'm not a peminat of any of them but I would say
Demi Lovato is the best her voice is very powerful
Then Miley Cyrus
Thhhhhheeeeeeennnnnnn.........
Selena Gomez

They all sound kinda the same to me....
But I guess Demi would have the best vocals.

It's my opinion that they all suck. With the exception of Demi.
I don't like her music, but her voice is nice.

-Demi
-Miley
-Selena

Demi has the best voice for sure !! Miley is also pretty good and Serena is ok but live tunjuk is ... ok
