how to know if song actually have an impact or not ?

we could look if the song is used in movies and dramas to see if it made an impact outside our Kpop bubble.

b...but some people need something to be proud off and brag about in their life

this!
for me
as long as I like the song of my favorite I can consume it

but of course
I want their song to be like by many
to have a chance to success to win awards sell a lot of album
because it important for an image or to be recognize as a brand

but no matter how many award they got or album they sell
if I can't like their song (multiple or consecutive of bad song)
I will remove them as my "top favorite"
example of that is ITZY or TWICE

but to have impact any had an impact
but what type of impact
national hit/global hit/ or just within their fandom

Quote from pwswan

Hangover was used in Black Panther and still didn't have an impact.

it was used as a backround sound with no relation to the movie tho. its not like t'calla danced or listened to it. the producer probably just googled random kpop song that could be played when the scene changed to busan.^^

If my grandma knows it

well ig how long it is on charts & maybe social media presence

and views/streams
