Finally Hyelin-unnie hit that high note! Omg, it's so nice to see how much they've improved since then. I love this song and Every Night more than Ah Yeah and Hot Pink tbh. I'd say my ranking would be 1. up and down, 2. Every night, 3. I feel good. This song also sounds like something you'd hear in the west like in the 2008-2010 years (:
