What do you think is necessary for a group to last for a long time ?

For girl groups, a large fanbase, that is more female oriented and the GP support/awareness.

For boy groups, you just really need a large fanbase. The GP is not really a factor for longevity, at least as a group.

A company that ain't trash. Looking at you YG.

Why do you think it is necessary for a human to have a long life? Is it? Is it not? We can't answer that

a fan base that's starving for content, music that to some extent evolves with time, not suddenly going on hiatus when their popularity starts to decline 🗿
