Adele's "Rolling in the Deep" maintains its hold over the chart with Airplay Gainer honors for a fourth consecutive week. The song bullets at No. 2 on Radio Songs (134 million in audience, up 14%, according to Nielsen BDS) and registers a third frame atop Digital Songs (297,000 downloads sold, down 16%, according to Nielsen SoundScan).
 
Adele's "21" dominates the Billboard 200 for a ninth week.
 
Katy Perry's former five-week Hot 100 No. 1 "E.T.," featuring Kanye West, spends a third week at No. 2, while Pitbull's "Give Me Everything," featuring Ne-Yo, AfroJack and Nayer, rises 4-3. The song advances 4-2 on Digital Songs (212,000, up 14%) and jumps 8-6 on Radio Songs (87 million, up 22%).

The titles at Nos. 4-7 on the Hot 100 ascend one spot each: the Black Eyed Peas' "Just Can't Get Enough" (5-4); Jennifer Lopez's "On the Floor," featuring Pitbull (6-5); Bruno Mars' "The Lazy Song" (7-6); and, Britney Spears' "Till the World Ends" (8-7).
 
Two songs blast into the Hot 100's top 10, led by LMFAO's "Party Rock Anthem," featuring Lauren Bennett and GoonRock, which soars 20-8 with the list's Digital Gainer award. The track charges 13-4 on Digital Songs (163,000, up 68%) and continues its rise on Radio Songs (44-40; 29 million, up 20%). The Los Angeles dance/rap duo - Redfoo (Stefan Gordy) and SkyBlu (Skyler Gordy), the son and nephew, respectively, of Motown Records founder Berry Gordy -- had previously peaked as high as No. 31 last August as a featured act, with Fergie, on David Guetta and Chris Willis' "Gettin' Over You."
 
Lupe Fiasco logs his second top 10, as "The Show Goes On" surges 12-9 in its 21st week on the Hot 100 (marking the chart's lengthiest top 10 ascension since Kings of Leon's "Use Somebody" reached the region in its 26th frame in August 2009). The rapper bests the No. 10 peak of his sole prior top 10, 2008's "Superstar" (No. 10), featuring Matthew Santos.
 
Chris Brown's former No. 6-peaking "Look at Me Now," featuring Lil Wayne and Busta Rhymes, rounds outs the Hot 100's top 10 (9-10).
 
Lady Gaga's "Hair" whips up a No. 12 start as the Hot 100's Hot Shot Debut. The song is the fourth to chart from her album "Born This Way," released yesterday and due to roar in atop next week's Billboard 200.
 
"Hair" bows at No. 5 on Digital Songs (147,000). Unlike the first three Hot 100 entries from "Born This Way," the song is intended solely as a digital preview track and is not being promoted to radio.

"The Edge of Glory," the third proper single from "Born This Way," falls 3-19 in its second week on the Hot 100, as its digital sales drop by 64% to 98,000. On Radio Songs, however, "Glory" vaults 54-37 (30 million, up 52%).
 
Nine other songs enter the Hot 100, including three by the "Glee" cast: "Pure Imagination" (No. 59), "Back to Black" (No. 82) and "My Man" (No. 94).
 
Other notable debuts include Nicole Scherzinger's "Right There," featuring 50 Cent (No. 77), as performed last Thursday (May 19) on "American Idol"; Rihanna's "California King Bed" (No. 80), the ballad follow-up to three No. 1s from her album "Loud": and, Jason Derulo's "Don't Wanna Go Home" (No. 92), which samples "Banana Boat (Day-O)," a No. 5 hit for Harry Belafonte on the Hot 100's predecessor chart the Top 100 in 1957 (and revived on Lil Wayne's recent No. 9 Hot 100 hit "6 Foot 7 Foot"). "Home" additionally samples Robin S.' "Show Me Love," which reached No. 5 on the Hot 100 in 1993.
