Aaron Smith is an American producer whose name reached the world through one track and, crucially, one remix of it. His original "Dancin", a breezy dance song featuring the vocalist Luvli, existed quietly until a 2014 reworking by the production duo Krono transformed it into a sleeper hit.
The Krono remix, with its warm, propulsive groove, became a slow-building international success and a TikTok and playlist staple, the version almost everyone now knows. It dwarfs everything else released under Smith's name.
On streaming, the "Dancin" remix sits near 1.1 billion plays, while his next genuinely different track trails far below. That sends the ratio above 27, many times our 5.0 line.
By our measure Aaron Smith is a certified one-hit wonder, with the streaming-era twist that recurs across this list: the version of his song that defines him is a remix built by other hands. He wrote and recorded the original, but it was Krono's reworking that turned it into the durable hit it became. A decade on, that remix still accounts for nearly all of his streams, while the bare original he first released lingers in its shadow.
