I would like to kindly point out that Bobby WON SMTM3 at age 18 when he could have joined high school rapper. Here's a thread of satisfying Korean comments from the YGGR stage, enjoy

"It is legendary because Bobby was only 19 (Korean age) performing this stage kkkkk. It only because they made a program called HSR recently, from the time when Bobby won 1st SMTM in the beginning in his teens he was already a legend"
"If we look back at the history of SMTM, Bobby was the origin of making the show popular among the general public. Even programs like Unpretty Rapstar and HSR were only possible because of Bobby."
"The fact that at 19 when he could have gone on HSR, he went on SMTM and did it like that without featuring artists, I can only say that he is amazing
+ he was doing yg survival M&M at the same time"
+ he was doing yg survival M&M at the same time"
"He really filmed ‘8 mile’ on his own kkkk. This stage presence is fxxking dope for real. At the time he was 18, he won SMTM when he could have gone on HSR kk"
"One of the reason of why he is great is that Bobby could have gone on HSR at that age kkk Only 18 years old + having an idol label and was looked down on + he was doing Mix and Match = Killed SMTM and won it. A great story people had to fall for, you can make a movie for real."
"At the age when kids on high school rapper are wearing helicopter caps and are trying out weird concepts, he won SMTM on his own with real hip hop stage presence. He was actually so fxxking cool."
You can see may of these tweets have many likes and are quite recent even though the performance was posted 7 years ago.
Fyi, on CJ ENM which Mnet is under released their 2021 content lineup, SMTM10 is under ‘music’, HSR4 is under ‘entertainment’
