Meanwhile, airplay is soaring for "Space," which bounds 9-5 in just its third week on Radio Songs (89 million, up 26 percent). How rare is a three-week ascent to the Radio Songs top five? In the last 13 years (to use Swift's favorite number), just one other single had reached the region in three or fewer weeks: Lady Gaga's "Born This Way," which needed only two, in 2011. Prior to "Born," no song had zoomed into the Radio Songs top five so, um, swiftly since Destiny's Child's "Survivor" did so in its third week (March 31, 2001). A week earlier, Janet's "All for You" had hit the top five in its second frame.
