John Perlman chats to Randall Abrahams who is a walking encyclopaedia when it comes to music knowledge. In this feature Randall selects a song and unpacks something significant about the singer/band, the lyrics, the instruments, the arrangements, or simply tells us why we should enjoy the song. Today’s song is Komasava by Diamond Platinumz, Jason Derulo ft Khalil Harrison and Chley.
