[All] I'm listening to Girls' Generation's party song

A while ago, I was at a mart and a Girls' Generation party song came on. Even though it had been a long time since I heard it, the song was so exciting and good.

I looked up what song it was and was so surprised to see that it was from 2015. It'll be 10 years old next year.

It's a song that's over 9 years old, but it's trendy and fun to listen to, like a song that came out recently.
