Give it up for the Queen of the Collabo! Guest appearances are the glue that holds the world of hip hop together. Artists appearing on one another’s tracks is a form of currency, both figuratively and literally, which makes Nicki Minaj one of the richest gals around. Kanye West, Drake, Trey Songz, Urshr, Ludacris, Britney Spears … she’s collaborated with nearly every big name the top 40 has to offer, often stealing the show with her distinctive, raunchy and schizophrenic delivery. The fascinating thing about Nicki is that her debut album was received well, but not really well, as if people fell in love with her only in small doses. I think Pink Friday captures her personality perfectly … cutesy one minute, fierce the next, and always captivating. Check out her album, and in honor of Collaboration Week, check out my favorite Nicki guest verse, on “Bottom’s Up” by Trey Songz.
