DBSK makes a comeback with Spellbound, and who cares because their backup dancers are really hot.
I actually like the song. The jazzy rhythm is good, and it is a nice turning point for DBSK, who probably took their dubstep/EDM style as far as it could go before they started looking like Super Junior without always having the same style of song for every comeback. However, the chorus for the song sucks, but the I like the rest of it. It usually goes the other way around with Kpop songs, but this is one of the exceptions.
However, the only reason why you should care about this music video is because of the backup dancers. They are hot. SM finally figured out a way to get males to watch a boy band music video. So the next time your dad/grandpa/uncle/brother/cousin/friend walks in on you and asks you why you're watching this gay shit, you can say "You can't use the 'gay shit' label this time because the backup dancers are hot."
I hope SM debuts some of these girls in a new girl group. They don't even need any good vocalists or anything. They can do what some of those Japanese idol groups do and just have one or two vocalists and just let the dancers dance...except this would be better because there wouldn't be any yaeba to ruin the fucking music video.
