Months after the release of “Disaster,” JoJo has finally premiered her brand-new single “Demonstrate!” The track will serve as the second official single off her long-awaited third studio album, Jumping Trains. After racking millions or views with her cover of Drake’s “Marvin’s Room,” the 21-year-old singer-songwriter has teamed up with Noah “40” Shebib, the original producer of the grown and sexy tune. “Demonstrate” has all the makings of a flawless chart topping r&b jam but will most likely not find a home in the mainstream Top 40. Production, lyrics, and vocals are all on point. What do you guys think?
