18. and Roger Williams' "Born Free" at No. 5.
19. At the time, Uncle Kracker's version of "Drift Away" (originally a pop and AC hit for Gray in 1973) held the record for the most weeks at No. 1 on the AC chart: 28. "How long was it No. 1?," he asked Billboard in 2011. "You sure Kelly Clarkson hasn't kicked my ass?"
20. It was actually Maroon 5 that ultimately claimed the longevity record atop the AC chart: "Girls Like You" reigned for 36 weeks beginning in November 2018. (Clarkson's "Breakaway" booted all contenders from the top spot for 21 weeks in 2005.)
21. While "Drift Away" represents a hit that has been embraced on AC radio for decades via its different iterations, some songs that might be expected among the chart's biggest hits never reached the ranking at all. "For example, the world's No. 1 rock group, The Beatles, did not have a chance at making the AC chart in 1965 with their plaintive song 'Yesterday'," Whitburn wrote in the 2001 edition of his Top Adult Songs chart reference book. As Beatlemania swept the U.S., and the Hot 100, the AC chart was still home to well-established crooners such as Dean Martin and Jerry Vale, both of whom scored AC No. 1s in 1965.
"The AC chart has continually represented the calmer alternatives to heavier pop-music movements (British Invasion, disco, punk, rap, grunge)," Whitburn mused. "Though the name of the category may change, there will always be music of the moment that is soft and sweet."
22. By 1970, The Beatles hit No. 1 on the AC chart with "Let It Be," while follow-up "The Long and Winding Road" hit No. 2.
