Jon Bellion needs a caveat up front. As a songwriter and producer he is one of the more successful figures in modern pop, with credits on enormous hits for other artists, so reducing him to a single song misses much of his importance. But our measure looks only at his own releases, and there one track dominates.
That track is "All Time Low", his shapeshifting 2016 single, a restless, genre-blending pop song that became his biggest solo hit by a clear distance. It marked him as a distinctive artist in his own right, even as his behind-the-scenes career flourished.
The rest of his solo catalogue trails well behind. On streaming, "All Time Low" sits near 780 million plays, while his next most-streamed track, "Guillotine", trails at around 153 million. That puts the ratio at about 5.1, over our 5.0 line.
So by our strict, numbers-only measure, Jon Bellion registers as a certified one-hit wonder, counting only his own releases. It is a narrow lens on a broad career: a sought-after hitmaker for others whose single biggest song under his own name has, on streams, pulled just far enough ahead to tip the maths.
