I like Metallica a lot. Do you like Metallica?
Yes I do, I like metal rock bands that are of American origin
My favorite album by them is probably Ride the Lightning. Do you listen to them frequently?
Not lately, do you know that the group was formed  in  1981 by drummer Lars Ulrich and  the vocalist?
Yes, they have been around for quite some time. 
Yea, i still love their first album "Master of Puppets"  which was released in 1986
I liked the orchestral collaboration they did , S and M. It was definitely an interesting take on their songs.
Oh yea? :),  talking about sales success  they have 16 million copies in the United States to date
That's pretty amazing, but it doesn't surprise me.
Ah, there is something new with them it's called thrash metal  and their ninth album, "Death Magnetic" (2008)
