It's so amazing! I love the soft piano verses and the hard guitar rock sound of the chorus. The MV visuals are also something else. You really could take a screencap of anything of it and you'd have an awesome wallpaper.
As much as I love Deja Vu though, I'm absolutely floored by how good Silent Night is from the album. It's easily my favorite song, and I really really love the rest of the album, it's just that good! Everyone do yourself a favor and listen to it, and the whole album while you're at it!
Also, first time posting on K-Pop ERA, never thought to see if there was a K-Pop group on here for some reason. I'm excited to find it though and join in the conversation.
