Digital Underground were an American hip-hop group whose place on this list undersells their real importance. Led by the late Shock G, they were colourful, funk-soaked innovators of West Coast rap, and they famously gave a young Tupac Shakur his start. They are anything but a novelty footnote, which is exactly why the caveat matters.
But streaming gathers around one comic anthem. "The Humpty Dance", released in 1990, is a gloriously silly, P-Funk-sampling party track sung in the nasal voice of Shock G's alter ego Humpty Hump, and it became their signature hit.
On streaming, "The Humpty Dance" sits near 122 million plays, while their next most-streamed track, "Same Song", trails at around 20 million. That puts the ratio above 6, past our 5.0 line.
So by our strict, numbers-only measure, Digital Underground register as a certified one-hit wonder, and we flag the caveat firmly. This was an inventive, influential group with a real catalogue and a lasting place in hip-hop history. It is only that one irresistibly goofy anthem has gathered the streaming crowd far ahead of the rest of their work.
