1. Drake - "Forever"
"Forever" is not just a summer jam, it's a hip-hop collaboration of mammoth proportions, an amalgamation of heavyweights. For the sake of argument, yes, Eminem wrecked this song with lines like: "There they go, back in stadiums as Shady spits his flow. Nuts they go, Macadamia they go so ballistic whoa" and "When I slap the bass out your mouth with a taste so great that it shakes the place."
