Since launching in 1979, the Nickelodeon network has not only introduced us to some of the most popular characters in the children’s television universe, it’s thrust cartoon music into the modern age. It’s no overstatement to say some parents know the lyrics to the pop-punky PAW Patrol jingle as well as they do the names of their own offspring, while the irreverent ditties in the Spongebob Squarepants songbook could almost pass for the work of a weirdo indie psych-pop act. But Nickelodeon isn’t just a playground for kids—R&B icons TLC, dancehall star Shaggy and roots rockers Los Lobos have all made contributions to its canon.
