As we’ve come to expect from Kanye West, new music can arrive at any minute, like when the rapper dropped new track “Only One,” featuring Paul McCartney, on New Year’s Eve. At the iHeartMedia Music Summit in Burbank, California on Thursday, Billboard reports West premiered his rumored duet with Rihanna to an audience filled with music industry figures. The rapper was a surprise speaker at the conference and treated the audience to a 45 minute stream of consciousness speech.
