When you start your chart life at No. 1, there's nowhere to go but down, but Eminem finds a way to rebound (11-8) with his former chart-topping debut "Not Afraid." Digital pre-order placement for the June 21 release of his album "Recovery" spurs downloads (157,000, up 13%) for the set's leadoff track as does increased radio play (up 7%), lifting the song back into the top 10 of the Hot 100 after a one-week respite.

Rounding out the top 10 are The Black Eyed Peas' "Rock That Body," which hold at No. 9 and Drake's "Find Your Love" which improves 13-10. "Love" is Drake's third top 10, all as a lead vocalist. He also visited the region with "Best I Ever Had" (No. 2 peak last July) and "Forever" (No. 8 in October).

Justin Bieber and Jaden Smith, star of the nation's No. 1 box office film "The Karate Kid," team up on the chart's top debut, "Never Say Never," at No. 33. The song, which plays during the closing credits of the film, sells 76,000 and opens at No. 17 on the Digital Songs tally.

The first "Glee" season has come to an end and the cast goes out on a consistent note for the year, with five more entries on the Hot 100, led by "Faithfully" at No. 37. The troupe's first Journey cover, "Don't Stop Believin' " also re-enters the chart at No. 59 as the "Regionals" rendition performed during the season finale accounts for 84% of the title's 51,000 total downloads. "Believin' " debuted at No. 4 on the Hot 100 in June 2009 and re-entered the list once before in September. In total, the song has spent seven weeks on the chart.

While some may ultimately remember the constant blaring of the vuvuzelas as the sound of the 2010 FIFA World Cup being contested in South Africa, a pair of songs emanating from the tournament are making chart noise. The competition's official song, "Waka Waka (This Time for Africa)" by Shakira featuring South African group Freshlyground debuts at No. 43 with 57,000 downloads. The track was performed during the Kick-off Concert in Johannesburg, broadcast by ABC on June 11, as was K'Naan's "Wavin' Flag" which moves 27,000 and re-enters at No. 89.

She performed the three tracks medley-style on the MTV Movie Awards June 6 and collectively they sell 97,000 downloads.

Lil Jon returns to the Hot 100 as a lead artist for the first time in over four years as "Hey," featuring 3OH!3, hops on at No. 70. The rapper last helmed an entry when "Snap Yo Fingers" peaked at No. 7 in May 2006.
