Since no one can agree on generations starting and stopping point I think a list for a decade is a better way of ranking things. And yes this also complicates things a bit since a lot can change in ten years. The popularity of kpop in 2011 compared to 2019 is night and day. So this is my first draft of the list and you all can chime in and say what you would change.
1. Girls Generation
2. Twice
6. T-ara
7. Sistar
8. Kara
9. APink
10. f(x)
Who should not be here? Who did I forget? Who should be rotated?
