Topp Dogg is a 13-member hip-hop boy group from South Korea created by Cho PD under the label Stardom. I'm still not familiar with them, and i dont know their name. Actually NONE of them i know. haha. I just love their work. I don't know their own song haha but fall in love with their cover, especially SOME by Soyou Sistar X Junggigo and Eyes, Nose Lips by Taeyang. Check this out !
