Rick Ross, Pharrell Aiming for Top Spots on Billboard 200 Chart

Rick Ross is on course for his fifth No. 1 album on the Billboard 200. The rap king's just-released set, "Mastermind," may sell between 150,000 and 160,000 copies by the end of the tracking week on Sunday, March 9 (so say industry forecasters).

Meanwhile, the red-hot Pharrell -- who leads the Billboard Hot 100 chart for a second week with his song "Happy" -- will likely debut at No. 2 with his new set, "G I R L." It might move around 90,000 to 110,000 copies.

The new Billboard 200's top 10 will be revealed on March 9.

The Oscar-nominated "Happy" (from the film "Despicable Me 2") has sold 2.1 million downloads so far, according to Nielsen SoundScan. "Happy" also doubles as the first single from "G I R L."

"G I R L" is Pharrell's second solo album, following 2006's "In My Mind." That effort debuted and peaked at No. 3 on the chart, selling 142,000 copies in its first week, according to Nielsen SoundScan.

For Ross, all of his major label-released albums have reached the top two rungs on the chart -- with only 2010's "Teflon Don" missing the No. 1 slot. His last release, 2012's "God Forgives, I Don't," opened in the penthouse with 218,000. 

Other albums aiming for handsome debuts next week include: Lea Michele's first album, "Louder," with maybe 50,000 to 60,000; and Eli Young Band's "10,000 Towns" with around 25,000.
