I think people sometimes forget because of NCT but actually SM boy groups usually chart well in Korea (at least during their peak).
TVXQ, Super Junior, Shinee, EXO were all regular chart toppers during their hey days with actual hit songs that the general public listen to. EXO hitting #1 with First Snow over 10 years later is a testament to the public’s longing for the older SM boy group sound.
This is not to say NCT don’t do well but if I recall correctly it took them a while to get an actual chart hit like NCT 127’s Kick it (4th year) or NCT Dream’s Candy (6th year) which just so happens to be a remake of a classic popular song by H.O.T, another popular SM boy group from 1st gen lol.
RIIZE charting shows that the public have been waiting a long time for another SM boy group with more “palatable” music and an easier to digest concept.
Them being this good at charting already reminds me of rookie Shinee with replay or rookie TVXQ with Hug, both songs of which were huge hits back in the day that earned them super rookie title. It’s no surprise that knetz constantly say RIIZE remind them of 2nd gen.
In other news RIIZE love 119 just reached #7 on Melon! Amazing to see the public open up to a new boy group after so many years.
