My favorite would be Avenged Sevenfold :D
the singer of that would also be my favorite haha :D I really like all types of rock. I mean I love rock, metal, heavy metal, screamo, death metal, and stuff like that, I would make a contest about some of those bands since they arnt really well known in the world. Most people only look at Justin Bieber, Miley Cyrus, Lady Gaga and I would like a challenge that would get people to explore more. Some of these bands would be: Avenged Sevenfold, Asking Alexandria, Three Days Grace, Metallica, and just stuff like that :D
