Netizen comments:

1.[+48, -3] Lies, Haru Haru, Heartbreaker, Tell Me, Sorry Sorry, Ring Ding Dong, Fire, and Gangnam Style were mega hits.

2.[+37, -13] Domestic and overseas fans of BTS line up everywhere to stream them. Melon, Spotify, Youtubeㅋㅋㅋㅋㅋㅋsome of them streal all day long.

3.[+32, 0] 2016 is the beginning of stream generation.

4.[+25, 0] There are a lot of songs in 2009 that became very popular among the general public.

5.[+16, 0] EXO is kinda inactive since 2017.

6.[+14, -3] As Gangnam Style became a hot topic all over the world, it appeared everywhere. When you turned the TV on, there was Gangnam Style. When you even watched the news, there was Gangnam style. He even performed Gangnam Style at New York Times Square and was praised a lot. Now BlackPink and BTS are becoming a hot topic all over the world and NCT and SuperM advanced to the US. A lot of idols appear on American broadcasts and have music videos with over 100 million views. At that time, after Gangnam Style, I thought Korean singers can get over 100M views easily. It seems that PSY really made a mark in the Korean music industry.

7.[+12, 0] I don't think there will be a singer like PSY. It's not a comparison with BTS but PSY became popular with the general public's recognition, not with fandom's.

8.[+12, -2] what if Lies, Haru Haru, Mirotic, and Gangnam Style was released today? Platforms like Youtube, Tiktok, and Melon are much more popular now. 

9.[+11, 0] Gangnam Style and Squid Game are the syndromes.

10.[+9, -1] What if Gangnam Style wasn't released in 2012?
