(CBS News) The Zac Brown Band's album "Uncaged" tops the Billboard chart for the second time, selling 48,000 units, according to Nielsen SoundScan.

This week was the lowest sales week for the No. 1 set since Nicki Minaj's "Pink Friday" hit to No. 1 with 45,000, reports Billboard.

Sales are expected to pick up next week with the release of rapper Rick Ross' new album "God Forgives, I Don't."

Behind Zac Brown Band on the charts is Nas' "Life is Good," Gaslight Anthem's "Handwritten" and Passion Pit's "Gossamer."
