I’ve lived in Korea since 2015 so I can give my unbiased opinion what which girl group songs I believe were the biggest of recent years. To be honest the top 2 are clear but I’d say 5-10 are pretty much interchangeable. I don’t think I’m forgetting anything
1. TWICE- Cheer Up & BLACKPINK - Ddu Du Ddu Du
3. BLACKPINK- How You Like That & TWICE - TT
5. Red Velvet - Red Flavor
6. Gfriend - Rough
7. Momoland - Bboom Bboom
8. BLACKPINK- As If It’s Your Last
9. BLACKPINK- Lovesick Girls
10. Twice- Dance the night away & BLACKPINK- Playing With Fire
