Girls' Generation is renowned for being the biggest and most successful K-Pop girl group of all time. They've conquered Korea and Japan with 7-years of smash hits and different styles. There's a reason they're the most popular girl-group, and this video proves why. This is my little tribute to them. I'm sure I may have missed some songs, or messed up some dates/album details, but my heart was in the right place. Also, some of the videos (like Bad Girl) only had terrible quality videos, so please forgive that. I'd love to know what your favorite SNSD song and album are :)
