Snoop Dogg can now include Stevie Wonder on his musical-legend collaboration checklist. His new song, “California Roll,” dropped on Tuesday and features the Motown legend on vocals, keyboard and harmonica. Produced by Pharrell, the song is a chilled-out ovation to the Los Angeles medical-marijuana program. In an interview with Yahoo Music, Snoop explained that getting Wonder on board was a bit of a coup and Pharrell was skeptical the 64-year-old would be interested.
