First off this is a completely old verse used by The Game for his new "Brake Lights" mixtape with DJ Skee, which was released today [download below]. The song "Street Riders" track, which also features Akon (besides The Game), features an old Nas verse where he goes at 50 Cent and Pharrell.
Either way, you can listen to the old verse below along with download the new mixtape!
