Taeyeon teased fans with the cover of Girls' Generation's upcoming Japanese best-of album, 'The BEST'!

She posted the above picture on Instagram as well as the message, "Girls' Generation 'The Best' 2014.7.23. I'm going to buy this too. Because if you have this, you can go through all of what Girls' Generation did until now. And the new song that will be released with it... I teared up because I liked it so much. #GGTheBest#GGJPN#Sunnytrytoflexevenmore."
