Young Jeezy's "Leave You Alone," featuring Ne-Yo, lifts 4-3 on R&B/Hip-Hop Songs, while LoveRance's "UP!" moves down (or, "DOWN!") to No. 4 from its No. 3 peak to date.

In its 38th chart week, "Drank in My Cup" rises 7-5 on R&B/Hip-Hop Songs, giving Kirko Bangz his first sip of the chart's top five.

Gospel sister duo Mary Mary set the standard for patience when "God in Me," featuring Kierra "KiKi" Sheard, reached the top five in its 43rd week in September 2009.
