For example my BLACKPINK bias is Rosé and love her to pieces but her solo music just doesn't have the same replay value for me as much as BLACKPINK's music; the only solo song of her's that I really replay the most is Hard to Love. Like if I wanted to listen to a solo idol's music i would stan a solo idol. I stan for group music mainly. Also a solo idol's music is normally supbar and half baked compared to the music they do as a group.
Imo the only time a solo music from a group member that matched the quality of the group they're from was Seulgi's 28 Reasons.
