RAP UP: With six No. 1s as a soloist and two as a member of D12, Eminem leads the Billboard 200 under a third billing. Bad Meets Evil, in which Eminem teams with fellow Michigan rapper Royce da 5'9", bows at No. 1 with the "Hell: the Sequel" EP.

Dating to the first rap album to top the Billboard 200 - Beastie Boys' "Licensed to Ill," which began a four-week reign the week of March 7, 1987 - 552 albums have led the survey.

"Hell," however, is just the sixth by a rap duo.

Here is a recap of all six sets by rap twosomes to top the Billboard 200:

Artist, Title, Date Reached No. 1, Weeks at No. 1
Kris Kross, "Totally Krossed Out," May 23, 1992, two

Tha Dogg Pound, "Dogg Food," Nov. 18, 1995, one
Big Tymers, "Hood Rich," May 18, 2002, one
OutKast, "Speakerboxxx/the Love Below," Oct. 11, 2003, seven
UGK, "Underground Kingz," Aug. 25, 2007, one
Bad Meets Evil, "Hell: the Sequel" EP, July 2, 2011, one (to-date)

DOUBLE DOLLY: One Dolly Parton classic returns to a Billboard ranking, while another may soon scale its first survey.

"The Voice" contestant Vicci Martinez debuts on the Hot 100 at No. 76 with her cover of "Jolene." Parton's introductory Hot 100 hit reached No. 60 the week of March 2, 1974. Already established at the country format by then, "Jolene" became Parton's 34th Country Songs entry and her second No. 1, following 1971's "Joshua."

Parton releases her 41st studio album, "Better Days," June 28. The set's first single, "Together You and I," updates her 1974 duet with Porter Wagoner. The original recording appeared on the pair's album "Porter 'n' Dolly." Although the song never graced a Billboard chart, the duet set yielded the Country Songs No. 1 "Please Don't Stop Loving Me" (Oct. 12, 1974).

HE'S THE MANILOW: A fellow veteran of '70s superstardom soars onto the Billboard 200, as Barry Manilow's "15 Minutes: Fame... Can You Take It?" arrives at No. 7.

The singer/songwriter's first studio album of original compositions since 2001's "Here at the Mayflower" marks his 13th top 10 set. Manilow notched his first seven such albums between 1974 and 1979. He didn't return to the top tier until "Ultimate Manilow" reached No. 3 in 2002.

"15 Minutes" is Manilow's first album of all newly-written material to reach the top 10 since "One Voice" peaked at No. 9 in 1979.
