She is pretty and her voice is strong with a reasonably good range, but with no variations or character to it other than steadily conversationally pleasant .Still, I could see her possible making the lives, because her sound is marketable. I actually liked these clips(with the exception of Dont Stop Believing, which sounded like a bad Glee audition because her voice is just not made for that kind of song).
I think she would be great as a member of a girl band, or on some trance style tracks, where vocals tend to have the kind of non varying tone and level throughout like she did through all these song clips.
I There is no one else performing this style this year, which also works in her favour. Itwill be interesting to see how she sounds now.
