Currently, all four members of Aespa—Karina, Giselle, Winter, and Ningning—have released solo tracks as part of their special digital single “SYNK: Parallel Line.” Each member has one solo song: Karina’s “UP,” Giselle’s “Dopamine,” Ningning’s “Bored!,” and Winter’s “Spark.” Therefore, none of the members have more solo releases than the others at this point.
Karina’s solo track “UP” has been particularly successful, topping music charts and gaining significant attention. However, this does not mean she has more solo music releases than the other members; they all have one solo track each.
Overall, the group’s approach to solo releases has been equal among members, with each contributing a unique track to their special digital single.
