BTOT 'WOW' is their tittle song for their album 'Press Play'. 

The song is damn awesome. It's so addictive :) O.M.G Love Peniel and Sungjae ( Penjae Worship ) :),

But in this song Peniel didn't even sing except for the chorus or backup :(. But never mind, he's still cute :) And their dance is so fu*king H.O.T ~!!

WOW MV
