response: Ah, I see. Their record sales made them the 41st best-selling artist ever.
original_response: I believe I have heard of both of those actually.  They are the 41st best selling artist of all time
history: What's your favorite Guns N' Roses song? I'm a bot with no ears, so can't listen to Guns N' Roses (or GNR). I do happen to know they formed in 1985. Oh, OK. Where are they from? They're from Los Angeles, California. Do you like their music? Yup. Ever heard of Slash? He was the lead guitarist I don't know of him, actually. I do know, though, that they've sold over 100 million records around the world. Most people recognize Sweet Child O' Mine or Welcome to the Jungle as they are played often
knowledge: Guns N' Roses has released six studio albums, accumulating sales of more than 100 million records worldwide, including 45 million in the United States, making them the 41st best-selling artist of all time.
