While I am completely YG biased, and a hardcore VIP, I don't think it's fair that everyone uses this video and compares it to Exo's in hopes of making them look bad. There are a few reasons why this is inaccurate:
1. Taeyang isn't dancing. Exo almost always has complex dance routines to go with their songs, and this can make it hard to hit every note perfectly because you become out of breath. Taeyang has amazing and powerful vocals, maybe even more than some Exo members, but you can't really compare.
2. The style of Exo's music simply doesn't sound as good when the MR is removed. I don't mean this in a negative way. Because most of their songs have a more pop-electro style, they rely heavily on instrumental and music, more so than singing. Eyes Noes Lips is a ballad type song, so it relies heavily on vocals, not music. Why you would compare these songs in the first place is beyond me. That's like comparing Mozart to Nicki Minaj. You wouldn't compare those two in the first place, so comparing the MR removed version of Taeyang and Exo doesn't make sense either.
3. They're different artists with their own unique sound and style. And in the end, as long as it sounds good live, who really cares. When you mess around with key elements of the song like this, of course it's not going to sound as good as the original. If the song as a whole sounds nice, then that's all we need to worry about. Imagine a band. When all the instruments come together, it sounds good. Each has a different sound and role in the band. Now take an instrument out of the band. Some songs will still sound good, while others fall apart because they're missing something that brought the rest of the sounds together. Different songs. Different styles. They rely on different elements to succeed. So quit judging artists talent on these stupid MR removed videos and just enjoy their music for what it is.
