is the number one important thing, and it is also the most important factor for me to judge the quality of a singer :))))))))
Of course, prettiness is also important, but it's just a plus to beautiful voice, at most, second to beautiful voice. Oh, BTW, right song that matches a singer's style and voice is also extremely important, almost as important as beautiful voice.
Whitney Spears is very pretty, but I do not like her or her songs at all~~~~~~~~~~~.
