BILLBOARD - By spending a fifth week atop the Billboad Hot 100, Adele's "Rolling in the Deep" is the longest-reigning No. 1 sung by a woman and to have appeared on a Billboard rock chart since another rocking "Roll" song - Joan Jett & the Blackhearts' "I Love Rock & Roll" - more than 29 years ago. This is the 23-year-old's first number one song in her career.
