Long before “The Pop Professor” (also known as Justin Grant) had a mic, he had a cassette recorder parked next to the radio, finger poised on the record button. While other kids were memorizing multiplication tables, he was memorizing Billboard charts. Instead of comic books, he devoured histories of Motown and the rock ’n’ roll revolution of the ’50s.

That obsession never left — it just got louder. From pop anthems to rock rebellions, from disco fever to hip-hop dominance, he’s spent a lifetime studying the songs that defined us and the stories behind them. Now, he’s here to turn all those years of chart-watching, crate-digging, and lyric-scribbling into a classroom where the lesson plan is simple: pop isn’t just music, it’s history in motion.
