The Jordanaires were an American vocal quartet, members of the Country Music Hall of Fame, best known as the backing harmonies behind Elvis Presley on a long run of his classic recordings. Their place on this list is a quirk of how those credits appear on streaming, where one Elvis ballad they sang on is filed under their name.
That song is "Love Me Tender", the tender 1956 hit on which the group provided the soft, supporting harmonies that helped define its sound.
On streaming, "Love Me Tender" sits near 209 million plays, while the next track credited to them, another Elvis-era recording, trails at around 17 million. That sends the ratio above 12, far past our 5.0 line.
By our measure The Jordanaires register as a certified one-hit wonder, with a large caveat: they were a celebrated backing group whose harmonies grace dozens of beloved records, not a lead act with a catalogue of their own. The songs filed under their name are essentially Elvis recordings they appeared on. It is simply that one immortal ballad has gathered the streams far ahead of the rest of their supporting work.
