Tryna pick up where the Eminem show left off
But I know anything's possible
Though I'm not gonna top what I sold, I'm at the top of my game
That shit is not gonna change, long as I got Dr. Dre on my team
I'll get away with murder
Bolded for emphasis.
He's at the top of his game/not gonna top what he sold, could either mean he's performing at the highest skill or he's at his biggest and the previous sentence (not gonna top what I sold) seems to imply that he meant biggest.
As long as I got Dr. Dre, I'll get away with murder
Or making fart sounds, and spitting almost nonsensical rhymes on the song.
Encore did sell 8 mill copies domestic, IIRC.
Honestly dunno how anyone can think My First Single is wack, btw.
