Way back 2010 when I was still a newbie Sone, I remembered watching SNSD FMVs on youtube and what I love about it were the songs that's being used by the uploader as the background music and it played a big role in helping me to discover more kpop music other than snsd's.

I came across with this song called "First Kiss" which was used for a Taeny FMV! That moment when the song started playing I already fell in love with it (been in love for almost 4 years and still not getting tired of it haha) and I was like "Oh, it's an SNSD song..but wait, why am I only hearing Taeyeon, Jessica, Tiffany, and Sunny's voices? Where are the others?" and I searched for its title and bam! It's not an SNSD song and it was never sang by the group. It left me puzzled because the voices were identical to the four members, so when I did a further research I discovered that the song was actually made for SNSD to sing but due to certain reason (budget perhaps) it was canceled. 

And just two months ago, Sunny finally did a cover of this song
