Dumb Dumb

Red Velvet are making a comeback with their first full-length album 'The Red'. Their title song is called Dumb Dumb, which includes Red Velvet's signature off-beat vibe.
In the MV, the girls transform from office employees to clones and to factory workers.

I really like their song but I prefer Happiness and Ice-cream Cake, their songs are always catchy and the music video is very interesting especially this one and Happiness. I think the dance for this song is the best out of all of their other songs.

What do you guys think?
