So this actually my first favorito K-pop group but not my first I listen too and even before I would say I might have had a lot favorito lines from these's girls lol. I always listen to them time to time and never got tired of their catchy songs and great lines. When comes to bias I actually went back a couple things to see who my Girls Generation bias was so far Jessica and Tiffany really got my attention the most since they where two of the girls I always loved their lines even before. I got to say I amor it when Hyoyeon and Seoohyun sing together, their two of my favorite's when it comes to two members cantar together. Taeyeon and all the rest are great too so it can be hard to have a bias but so far I would say Jessica and Tiffany for me. Though am still deciding so might not be the final decision lol. I don't care if Girls Generation is one of the oldest groups, I still amor them.
