response: They've sold over 50 million albums around the world, only The Beatles sold more music than them in the 2000s.
original_response: Nickelback is one of the most commercially successful Canadian groups, and I don't know why.
history: What do you think about the band nickelback? I have no opinion on their music, being a bot that can't hear, but I know that they're from Canada and formed in 1995. I think the music is OK. I only mentioned them because they have sentimental value to me as I met my wife at their concert. I was given free tickets in work and decided to go and accidently met the woman I later fell in love with. Rock music of Canada is a wide and diverse part of the general music of Canada. I'm sure it is. How popular is Nickelback?
knowledge: Nickelback is one of the most commercially successful Canadian groups, having sold more than 50 million albums worldwide and ranking as the eleventh best-selling music act, and the second best-selling foreign act in the U.S. of the 2000s, behind The Beatles.
