Macklemore & Ryan Lewis' "Thrift Shop" picks up a 12th week atop Hot R&B/Hip-Hop Songs, setting the mark for the longest-running No. 1 rap song in the chart's history.

DJ Khaled's "I'm On One," featuring Drake, Rick Ross and Lil Wayne, previously held the record with 11 weeks in 2011 and is the only other rap song to post double-digit weeks at the top.



"Thrift Shop" is still building in chart points, as it lifts 21% in download sales to 282,000 this week (according to Nielsen SoundScan). That means Macklemore & Ryan Lewis have a shot at the all-time record for the longest No. 1 for any title since the R&B chart became a single listing encompassing both airplay and sales in 1958. Mary J. Blige currently holds the record with "Be Without You," which spent 15 weeks at the summit in 2006.





Holding steady at No. 2 on Hot R&B/Hip-Hop Songs is Justin Timberlake's "Suit & Tie," followed by Drake's "Started from the Bottom" sitting tight at No. 3. Lil Wayne's "Love Me" is also a non-mover at No. 4, while Macklemore & Ryan Lewis' "Can't Hold Us" continues its climb, skipping 7-5 in its 19th week on the list. The act is the first duo/group to have a pair of singles in the top five concurrently since 112 on June 21, 1997. That week, the R&B quartet was at No. 1 as the featured act on Puff Daddy & Faith Evans' "I'll Be Missing You" and at No. 5 with their own single, "Cupid."



Back on the chart this week, Rihanna's "Pour it Up" stays put at No. 6, its peak position, for a fourth consecutive week, while A$AP Rocky's "F**kin Problems" slips 5-7 in its 23rd week. Wale's "Bad" moves 10-8 to establish a new peak and Ace Hood's "Bugatti" breaks into the top 10 jumping 11-9. This is Hood's third top 10 title behind "Hustle Hard" (No. 9 peak) and "Body 2 Body" (No. 6 peak) and the fastest of the three to reach the region. His We The Best/Cash Money debut album "Trials & Tribulations" is due July 16.



Over on Top R&B/Hip-Hop Albums, Justin Timberlake's "The 20/20 Experience" holds the No. 1 position for a second week with 318,000 copies (down 67%, according to Nielsen SoundScan). Lil Wayne's "I Am Not a Human Being II" opens at No. 2 with 217,000, marking his 11th top 10 album on the chart. For comparison's sake, Wayne's last studio album "Tha Carter IV" sold 964,000 copies in its first week of availability in 2011 but the previous "I Am Not a Human Being" opened with only 110,000 (as a digital exclusive in its first week). "Tha Carter" albums seem to be his flagship releases.



Macklemore & Ryan Lewis' "The Heist" retains the No. 3 position with 30,000 copies (up 24%) while Rihanna's "Unapologetic" slips 2-4 with 28,000 (up 6%). Kendrick Lamar's "good kid, m.A.A.d city" rounds out the top five with 16,000 copies (up 12%).



Further down Top R&B/Hip-Hop Albums, Papoose's debut album "The Nacirema Dream" opens at No. 13 with 5,000 copies. After a slew of critically-acclaimed mixtapes, the Brooklyn rapper signed to Jive back in 2006 for a reported $1.5 million but disagreements with the label shelved the album indefinitely. Papoose left Jive in 2007 and continued to release mixtapes, totaling nearly 30, until he could independently release "The Nacirema Dream."



Kansas City rap duo Ces Cru also post their debut full length album "Constant Energy Struggles" at No. 14 on the list with 5,000 copies. They previously charted at No. 26 on the list with their "13" EP selling 3,000 copies in 2012. Before signing to Tech N9ne's Strange Music label, Ces Cru rappers Ubiquitous and Godemis were frequently featured on N9ne's albums including his No. 1 "All 6's and 7'"s in 2011.
