Lynn Anderson was an American country singer whose place on this list undersells a genuinely successful career. A star of the 1970s with many charting songs and major awards, she was a fixture of country radio and television, which makes the lopsided shape of her streaming profile a modern phenomenon rather than a verdict on her work.
Her one streaming giant is "Rose Garden", released in 1970, a bright, philosophical crossover hit, all sunshine and hard-won realism, that topped country charts and reached far into the pop mainstream around the world.
On streaming, "Rose Garden" sits near 112 million plays, while her next most-streamed track trails at around three million. That sends the ratio above 42, far past our 5.0 line.
So by our strict, numbers-only measure, Lynn Anderson registers as a certified one-hit wonder, and we flag the caveat clearly. This was a major country artist with a deep catalogue and a wall of awards. It is only that one sunny, internationally beloved crossover song has gathered the streaming crowd so far ahead of the rest that it now stands almost alone.
