Best Viral Hit That Propelled An Unknown Group To Fame

Just made a thread about groups I didn't think would make it as far as they are now, and someone mentioned Brave Girls. After I watched the viral video that blew them up, I realized what a BOP that song is. This song literally put Brave Girls on the map, and so I wondered, if we compare the songs that took virtually unknown groups and introduced them to the public, which ones come out on top.

Only ones I can think of are Bboom Bboom by Momoland, Up and Down by EXID, Crayon Pop Bar Bar Bar, and Rollin' by Brave Girls. Which one is the QUEEN of viral hits. (Let me know if I forgot one, and I'll add it.)

Also...that Up and Down video is suggestive af?! Did Korea really approve this?

Quote from SooYoung

Brave girls and in second place EXID

Boom boom and Bar bar were good viral hit but that's it, they didn't propelled their group to fame since they have been flopping after these songs

meanwhile Brave girls and EXID became very popular GG after the success of their viral songs

I think they still count. Momoland and Crayon Pop were famous for a bit. They just couldn't retain their popularity. Fame does not always mean longevity.
