All youre demonstrating is that you judge singing primarily on whether you like someones vocal tone or not. Thats a poor way of judging how good a singer is as tone is just what youre born with and has no bearing on how technically skilled a singer is.

Here Coco was casually singing whilst pampering herself in the mirror ad still did a technically solid job. Well controlled vocal, clearly defined runs and solid breath management. She objectively can sing well. How pleasant you find her vocal tone is subjective and besides the point.
