3. Los Del Rio, "Macarena (Bayside Boys Mix)"
The Spanish pop duo Los Del Rio had been together for three decades by the time they wrote their biggest hit, "Macarena," in 1992. But it took four years and several different versions before a remix with English language verses became the worldwide dance phenomenon with the longest climb to Number One in Hot 100 history, peaking after 46 weeks(!) on the chart.
