Sam Haft is an American composer and songwriter who, with his collaborator Andrew Underberg, wrote the music for the animated series Hazbin Hotel. His presence on this list rests on one breakout song from that score, and like several soundtrack cases here, it sits a little apart from a conventional solo career.
That song is "Poison", from the 2024 Hazbin Hotel soundtrack, a dark, theatrical number performed by cast member Blake Roman. It struck a chord far beyond the show's audience, becoming a substantial streaming hit on its own.
On streaming, "Poison" sits near 212 million plays, while the next most-streamed track tied to Haft trails at around 14 million. That sends the ratio above 15, far past our 5.0 line.
By our measure Sam Haft is a certified one-hit wonder, with the caveat that his work is that of a behind-the-scenes composer rather than a performing artist. The other songs in his catalogue are also from Hazbin Hotel. It is simply that one theatrical, much-shared track broke out far beyond the rest, and on streams it stands well ahead of everything else bearing his name.
