was released as an extended play (EP) in the United States through Masterbeat.com on June 2, 2010, to the iTunes Store on July 13, and in the United Kingdom through Amazon on June 29, 2010. These EP's consist of remixes by various DJs and music producers, including Dave Audé and Mark Picchiotti. Composition "Rockstar 101" is a grunge-crunk and hip hop song which lasts for three minutes and fifty-eight seconds. It features an "aggressive" guitar solo from Slash, according to Leah Greenblatt of Entertainment Weekly. Rihanna uses her lower register and "heavy" modulation to perform the most of the song, and she "growls" the lyric "The only thing I'm missing is a black guitar". Rihanna "struts her stuff" as she insists that she is a "big shit talker" as she proclaims that "I'll never play a victim/ I'd rather be a stalker". Sean Fennessey for Spin thought that when Rihanna sings the line "Got my middle finger up, I don't give a fuck", it sounded as though she had never sworn before due to how she preciously mewls the word 'fuck'. Critical reception "Rockstar 101" received mixed responses from music critics. Brian Linder for IGN praised the song, writing that it "actually works" despite sounding disjointed at first. Emily Tartanella of PopMatters defined "Rockstar 101" as a "brilliant bit of bravado" during her review of Rated R, while Ailbhe Malone for NME wrote that Rihanna sings with "swagger" on the track, which was something that she has Hova to thank for. Jon Pareles for The New York Times simply highlighted a line from the song, "I never play the victim". Neil McCormick for The Daily Telegraph thought that "Rockstar 101" was one of the few songs on the album to retain the "vaguest leftover hints of her warm Caribbean vocal flavouring". Ann Powers for the Los Angeles Times was critical of Slash's inclusion on the song, and she described it as an "afterthought". Powers wrote "she can definitely get by without that ultimate rock phallic symbol", a reference to Slash. Pitchforks Ryan Dombell felt that "Rockstar 101", alike "Russian Roulette" and "The Last Song", were "instantly-dated missteps from a bygone era when a Slash feature was cool". He further wrote that "Rockstar 101" and "G4L" were "harder to justify considering their mindless boasts and torpid production". The song was met with a negative review from The Guardians Alex Petridis, who
