I didn't say Iu needs to beat her own record to be a hit.
Like I said whether the song is a hit depends on how they chart normally.
IU can easily pull an 800k ULs on the first day and stable at around 500k - 600k( lilac and celebrity) after the first day easily.
If beating other artists and reaching a ULs that you normally can get is considered as a hit song then every IU song is going to be considered as a hit song because I mean who can beat IU in digital or ULs?? no one can easily pull an 800k ULs in the first day and being at the stable 500k - 600k ULs.
As I said, I expect better digital/ULs from IU to be considered a hit, but I don't expect a lot tho. I just expect the digital could stay between 700k - 800k
