One of my favorite songs is girls, girls, girls by jay z. Just Blaze produced it and i've been trying to figure out a couple of things. He samples the song "I Love You More and More Everytime" by Tom Brock, and it is evident that he takes the strings from that song and uses it for girls girls girls. But I don't understand how he is able to sample it because in the song by tom brock there are so many other things going on while the strings play like guitar, drums, etc. How is he able to do this?
