Kanye West made a surprise appearance at an iHeartMedia Music Summit in California, and reportedly previewed a new track with "All of the Lights" collaborator Rihanna while discussing his plans for 2015.

West was introduced by Def Jam CEO Steve Bartels and spoke for nearly an hour on his career path, plans for new music and his attempts to be a radio-friendly artist this time around, as his last album, "Yeezus" lacked strong radio singles. Kanye even told the room full of radio executives that he was "joking" during his last album rollout, when he said several times that radio "ain't where I want to be no more."

After an a capella performance of his new song "Only One," Kanye played just enough of his Riri collab to get people talking without fully debuting the track. Earlier this month, Ty Dolla $ign revealed that he, Kanye, Paul McCartney and Rihanna all have a song together. Whether or not this is the collab in question, we'll have to wait and see.
