Stack Bundles was a rapper from Far Rockaway, Queens, NYC who was murdered in 2007. He was good friends with Joe. Joe is paying tribute to him in these lines. Referring to the shades that Stack had on in his wake.
Joe would like to bring Stack on tour with him even if it means exhuming Stack from the grave.
He took either the 4, 5 or 6 trains in NYC to 86th Street and Lexington Avenue in Manhattan. Since he already used his Metrocard to pay the fare to get on the train, he put it back in his wallet. He then proceeded to walk to the Metropolitan Museum of Art.
