But it kind of goes both way, even if I agree that it's the group that make them individually popular, it's also their individually popularity and status that gives the group it's "staying power". Had the members not have the status they had Blackpink would not have been able to keep it's status for so long with so few songs and activity during the last couple of years. If you compare with Twice they have a much harder time too stay relevant at the top as soon as their song releases got fewer.
Agree that it is both way
BP the group and the 4 of them are not separable. No matter how the solo akgae try to push thE narrative that their fave is better as soloist. The moment they quit BP group, they will immediately lose a big chunk of support/attention from casual listeners.
The group also benefited from exposures brought by 4 of them as soloist. That's what kept them 'relevant' without BP group being forgotten
