Last year on tonight performance, Taeyang danced tight too much unlike other members, it's YG's fault. They sometimes put Taeyang too much burden, they need to give Taeyang time take a rest before his part. But they didn't, that's why Taeyang got our of breath often.
Vips're ignorant of Taeyang's vocal, and sometimes blamed on him with stupid reasons.
Taeyang didn't train his vocal to enlarge his vocal range, he trained to express better. Training to enlarge vocal range can cause vocal nodules and the simplicity of the voice. With that kind of vocal training, a singer can gain the stablity on live singing and amazing high notes but he/she loses the various groovy voices in the middle tone, as a result he/she can't express the songs with the right emotions.
In urban R&B genre, the various groovy voices and right emothions're the most important factors than hitting high notes.
Most of the world-best top R&B singers are the same with Taeyang because they also didn't train their vocals to enlarge the vocal range.
Usher raraly sings on his live because of the dancing, Rihanna is notorious for unstablity on live singing and she makes mistakes hitting high notes tons of times during singing. But they're regarded as the best because experts can see what is real music.
In korea, tons of ballad singers can sing live better and hit the high notes way better than them, they trained their voices to hit the high notes because koreans love hitting high notes. But their music is regarded as low quality by experts because of their voices, they can't express the emotions and songs right with their hoarse, weak and simple middle tone. That's why they sing all the songs with same style and their music is called "mass-produced" music. General ppl may think they're good singers for a while but experts DO NOT appreciate them, experts know they'll disappeared because ppl would quickly get tired of them.
I think vips're a bit ignorant of music and they often degrade Taeyang with stupid reasons. On the other hands, experts can see Taeyang's true value and always praise his live singing and his music with one voice.

 All right I get what u mean... But don't worry too much :)
I believe... even though ggl ppl're ignorant of music, if they have ears ... they'll love Taeyang's music no matter he's perfect or not. I love Taeyang for his music and for his emotions and feelings, for his voice not because he's perfect. Music is not math. I think we can't measure the greatness of music with the things like vocal range, making mistakes ...
I feel bad when some vips try to degrade him with those things, not-knowing about the property of each genre, not-knowing his true value. But I'm glad you're not a hater. I misunderstood you,,,
But you don't need to worry too much because most of the ppl love Taeyang's music, it seems only Taeyang haters/anti-fans try to hurt him except vips.
But it's really sad some vips also hurt Taeyang often for being short in understanding his music instead of protecting him from the haters.
