Hammarby is a Swedish soccer team Einar rooted for (south side Stockholm). Green and white are Hammarby’s colors and in this song he raps about selling white (coke) on the ”green line” (a subway track in Stockholm).
Hammarby is the soccer team with biggest amount of supporters in sweden, the colors of the team is green and white. When he says "sending white on the green line" its a reference to hammarby with the colors and white he obviously means cocaine and with the green line its the subway line were the city is in and dalen, skarpnäck etc.
Finally you back with a banger. Yes Einar was one hundred. He was defenitely street and though but as a person i sad him humble and loved his fans. So sad he got shot. People hated on him because he was white and from sweden. Believe it or not
