So I got inspired by JILBSLA's SHINee 10 day challenge, so I searched on Google and saw a 30 day teen Top challenge!

Although the chances of me completing them are close to none... 

Anyway...

Teen Top 30 Day challenge Day 1: The First Teen Top song you ever heard

Oh this one's easy. 

"Hey to you, to you, to you, now~"
