He is way better than majority of idols. It's not hate. Idols are trained in other aspects of their artistry, not just singing. They can dance, sing, some can produce and choreograph. It makes sense that a musician who solely focuses on his vocals and songwriting skills is better than them and has space to improve at a faster pace than most idols. It would be amazing if most idols had his vocal skill-set. I can't imagine how the kpop scenery would look like. Some idols can sing at the same level as him. Very few are maybe even better, but majority of idols don't come close to his vocals.
