Wow Way to Go is b-side song of Gee album which released on 2009 which some of the idol are still in primary school or middle school at that time like wow even now its still covered by new group. You can tell there songs are really good and meaningful that you can never forget even its a old song.
Man the generational Impact of SNSD Red Velvet covers the Genie and Gee Era while Ive and Itzy covers the Lion Heart era which they are probably still middle school or Highschool in 2015. That is a true testament tested by time 15 years of SNSD.
