That's three reasons why I like this girl: her voice, and the other two reasons.
Ah, yes, the classic Three Reasons to Like Katherine McPhee .... :)
It's obvious that people who didn't like her tent-like dress are not the same people who appreciate two of the three reasons!
(Just to clarify: *I* am not an appreciator myself of two of the three! But I have seen enough in life now to know what will play well to others.)
