Bun Trill OGCanadian rock band Arcade Fire was able to keep Eminem outta Billboard 200’s top spot, but the Detroit rapper still managed to move some units while Texas legend Bun B makes a splash in the top 5 with his new solo album.

While Arcade Fire sits atop the charts, Eminem’s Recovery holds steady at no. 2 for the second week in a row, selling another 152,000 copies.

A couple slots down, Bun B’s new album Trill OG lands at no. 4 to open with 41,000. It’s the rapper’s first release distributed through Universal’s indie arm Fontana, and has gained a lot of attention within the hip-hop biz after receiving the coveted 5 Mic “Classic” rating from The Source magazine in their latest issue. His previous album, 2008’s II Trill, debuted and peaked at no. 2 with 98,000.

Right behind Bun is Rick Ross, slipping two spots to no. 5 this week with Teflon Don, selling 39,000 copies; and Drake’s Thank Me Later comes in at no. 8 with 31,000, putting him just under 950K so far.

Closing out the top 20 is Usher’s Raymond v. Raymond, which lands at no. 17 with 16,000.

That wraps things up this week. To cop any of these new releases, head over to Amazon.com.

According to Billboard.com, overall album sales in this past chart week (ending Aug. 8) totaled 5.26 million units, up 1% compared to the sum last week (5.21 million) and down 13% compared to the comparable sales week of 2009 (6.04 million).
