Rihanna's 'Rockstar 101' is her fourth single off 2009's 'Rated R.' Carried by deep bass beats and dupstep samples -- as well as Slash's bass guitar -- the mid-tempo track has Rihanna singing about the grimy disposition of a rockstar. Rihanna performed The-Dream and Tricky Stewart-produced track recently on 'American Idol' during the Beatles theme week. 'Rockstar 101' follows the ska and steel drum-driven 'Rude Boy,' which references the stereotyped Jamaican bad boy. To hear the new single, tune into AOL Radio's New Pop First station.
