The party turns ugly on “After Party,” the Santigold-assisted cut from The Lonely Island’s second album Turtleneck & Chain, in stores Tuesday. After the last bottle of Dom is popped, frontman Andy Samberg asks himself, “What the hell am I doing with my life?” before spiraling out of control with teary-eyed calls to mom and plenty of self-gratification. Santigold joins the pity party, which ends with an epiphany (“You can’t spend your whole life jerking off”) and a relapse. Spare us the invite.
