The slim margin (roughly 500 downloads) between the top two titles on Digital Songs marks the tightest race atop the tally since Mariah Carey's "All I Want for Christmas Is You" and Eminem's "When I'm Gone" each sold approximately 41,000 the week of Dec. 24, 2005.
"Deep" claims the Hot 100's Airplay Gainer award, powered by its 12-7 advance on Radio Songs (77 million, up 24%).
Spears' "Till the World Ends" blasts 11-3, besting its previous peak of No. 9, as the Hot 100's Digital Gainer following the release of its much-buzzed-about remix featuring Nicki Minaj and Ke$ha. "World" roars 12-3 on Digital Songs with 246,000 downloads sold (up 102%). The triple-threat remix accounted for 167,000, or 68%, of the title's sales in the April 25-May 1 tracking period.

"World" marks the second high-profile remix - both involving Spears - to spur a headline-grabbing chart move in three weeks. Rihanna's "S&M" ascended 2-1 two weeks ago following the release of its remix featuring Spears. All versions of "S&M" sold a combined 293,000 downloads that week, a gain comparable (up 108%) to that of "World" this week. Likewise similar to "World," the Spears-assisted remix of "S&M" accounted for 66% of the song's overall digital sales that frame.
The Black Eyed Peas' "Just Can't Get Enough" dips 3-4 on the Hot 100, while Bruno Mars notches his fifth top 10 in as many tries, as "The Lazy Song" rises 6-5.
"S&M" slips 4-6 on the Hot 100, ahead of Jennifer Lopez's "On the Floor," featuring Pitbull (7-7). The latter song is expected to exhibit gains on next week's Hot 100 and Digital Songs charts after Lopez temporarily trades her judge's chair for the stage when she and Pitbull perform the track on "American Idol" tomorrow night (May 5).

The "Glee" cast scores the top three debuts on this week's Hot 100, led by its mashup of the "West Side Story" song "I Feel Pretty" and TLC's "Unpretty" at No. 22. On Digital Songs, "I Feel Pretty"/"Unpretty" starts at No. 13 (112,000). The ensemble's covers of Keane's "Somewhere Only We Know" (75,000) and Lady Gaga's "Born This Way" (73,000) follow at Nos. 42 and 44, respectively.
The "Glee" cast adds a fourth Hot 100 debut, "As If We Never Said Goodbye," at No. 80, while the original version of a song that the troupe remade on last Tuesday's episode, Duck Sauce's "Barbra Streisand," bows at No. 89 (30,000, up 149%). ("Streisand" topped Dance/Club Play Songs in December).
The show whose premiere last Tuesday beat "Glee," and all competition, in its timeslot, "The Voice," prompts the Hot 100 arrival of contestant Javier Colon, whose R&B-tinged take on Cyndi Lauper's "Time After Time" launches at No. 65 (46,000). One of the four coaches of the series accompanies Colon onto the Hot 100, as Maroon 5, fronted by "Voice" coach Adam Levine, enters at No. 100 with "Never Gonna Leave This Bed."
