Independent favorites Atmosphere made a splash on the Billboard Top 200 albums chart today (April 20), debuting at the No. 13 position.

While it was not group’s highest placement on the charts or its most-selling, it comes in second place in the collective's history, with 27,000, according to the Nielsen SoundScan report. 2008’s When Life Gives You Lemons, You Pain That Shit Gold, was it's most successful, selling 36,000 in its debut week and landing at the No. 5 spot.

Leading all hip-hop artists on the charts this week is Wiz Khalifa’s Rolling Papers. The 2010 XXL Freshman slipped three seats down from No. 5 to No. 8 this go-round with 36,800 copies of the disc falling off shelves in the last seven days. After three weeks, the Pittsburgh, PA MC sold about 294,300 units thus far.

Surprisingly, another rap artist doesn’t show up on the charts until No. 31. Nicki Minaj’s Pink Friday occupies that spot with a sales figure of 14,900. The Young Money princess now has a 21-week tally of 1,313,200.

Grabbing the No. 33 and No. 34 spot are Eminem and Lupe Fiasco respectively. Both Recovery and Lasers added 14,000 more units to their overall sales, which for Em now equals 3,802,700 and for Lu, 334,000.

Swollen Members failed to crack the Top 200 in their first week, but their new album, Dagger Mouth, did manage to sell about 2,900 copies.

Next week look for Cam’ron and Vado’s collaborative project, Gunz n Butta to debut on the charts. —Elan Mancini
