-- Eminem: His "Recovery" set is the still king of the Billboard 200 for a fourth week, shifting 195,000 according to Nielsen SoundScan. And, with his rise to No. 1 on the Billboard Hot 100 (see below), it's the first time a male soloist has concurrently held the two No. 1 slots since the charts dated Oct. 18, 2008, when T.I. reigned on both.

-- Band of Horses: iTunes premiered the band's new video for "Laredo" last week and touted the "Infinite Arms" album -- on sale in the store for $7.99 -- in its weekly email blast. In turn, the set snares the chart's largest percentage gain and second-biggest positional jump as it rises with a 45% increase, climbing 58 slots to No. 70.

-- Colbie Caillat: On July 16 the Amazon MP3 store offered the "Breakthrough" album as its daily deal for $3.99. It's up 32% overall and 104% in downloads, rising 35 rungs to No 71.

-- Clay Walker: The singer performed his top five Country Songs hit "She Won't Be Lonely Long" on the July 13 edition of "Lopez Tonight," likely sparking the album of the same name's first increase since its debut six weeks ago. It's up 21% and rises 19 spots to No. 90.

-- Point of Grace: Sales from the trio's performance at Premier Designs' 25th Anniversary Rally in Ft. Worth, Texas, boost the "No Changin' Us" album by a whopping 474% (a re-entry at No. 142). Premier is a direct sales jewelry company that was started as a way to support Christian ministries in the U.S. and abroad.

-- Brandon Boyd: Nearly falling off the chart in just its second week, the Incubus singer's "The Wild Trapeze" collapses 166 slots -- the biggest fall on the chart -- to No. 199 with a 75% drop in sales. Because the album has such limited availability (it's only on sale in iTunes' store and through Boyd's Web site) and since the project is fairly under-the-radar, a large sophomore-week drop was expected.

The Billboard Hot 100:

-- Eminem: The rapper posts the first back-to-back Billboard Hot 100 chart-toppers of his career as "Love The Way You Lie," featuring Rihanna, jumps 2-1. The rapper debuted atop the Hot 100 in May with "Not Afraid," the introductory single from his current Billboard 200 chart-topper "Recovery." "Love The Way You Lie" earns dual gainer awards with a digital sales increase of 12%, to a one-week high of 352,000 downloads, according to Nielsen SoundScan, and a 34% airplay spike to 25 million listener impressions, according to Nielsen BDS.

-- Katy Perry: While "California Gurls," featuring Snoop Dogg descends from its Hot 100 perch (to No. 2), it rises to the top of Hot 100 Airplay with 154 million listener impressions, becoming her first No. 1 on that tally.

-- Usher: He earns his second top 20 debut on the Billboard Hot 100 this year as "DJ Got Us Fallin' In Love" opens at No. 19. Song flies onto the chart with simultaneous high debuts on Hot Digital Songs (No. 17, 61,000) and Hot 100 Airplay (No. 31, 32.5 million impressions). The latter rank matches Perry's "California Gurls" for best start on that list since 2008.

-- Christina Perri: Live performance on FOX's "So You Think You Can Dance" results show on July 17 helps downloads improve by 40%, sending title 58-34 on Hot 100 and 23-13 on Hot Digital Songs (68,000). The young vocalist signed her first major label contract with Atlantic Records on July 21, with Roadrunner Records handling radio promotion for her titles.

-- OneRepublic: The band's new single "Secrets" flies 70-46 as increased radio play -- No. 36 on Mainstream Top 40 and a No. 38 debut on Adult Top 40 -- coupled with a performance on the July 13 "Regis & Kelly" and its use in the new "Sorcerer's Apprentice" film push download sales to 47,000 (up 66%). On the Billboard 200, the band's album gallops 61 slots to No. 123.

-- Kanye West: Hot 100 descent of "Power" (22-29-60) is attributed to digital sales outpacing radio play. Sales for the track have gone from 80,000 to 57,000 to 22,000 in its three weeks on the chart while radio listener impressions rose to 21.3 million from 15.7 million during the same time frame. Continued increases on the radio side could reverse the song's Hot 100 slide in the coming weeks.
