Adorable girl group Red Velvet isn't 'dumb dumb' when it comes to the music industry. The girls have another hit on their hands as they've topped music charts with title track "Dumb Dumb"!

"Dumb Dumb" has already reached number 1 on 7 main music charts including Genie,Olleh Music, Naver Music, Mnet, Soribada, Bugs, and MelOn! The other songs from their album 'The Red' are all ranking high as well, most notably "Oh Boy" and "Huff n Puff".
