Ke$ha claims the longest running No. 1 debut single by a female artist on the Billboard Hot 100 since 1977 as "TiK ToK" holds steady for an eighth week. 33 years ago, Debby Boone took her maiden Hot 100 appearance, "You Light Up My Life" to No. 1 for 10 weeks. The Black Eyed Peas inch closer to another No. 1 single, as "Imma Be" moves 4-2, while their Grammy-winning single "I Gotta Feeling" leaps back into the Top 10 after their performance on the awards show. Other artists receiving a Grammy bump include country group Lady Antebellum, as their single "Need You Now" moves from 8-3, and Pink, who sees her album cut "Glitter in the Air" debut at No. 18 on the strength of digital sales. Young Money's "Bedrock" and Lady Gaga's "Bad Romance" round out the Top 5.
