The Roc is in the building.  Rihanna calls on her Roc Nation boss Jay-Z for “Talk That Talk,” the third single and title track from her sixth album.  RiRi squats down on the gritty black-and-white cover, which she revealed on Twitter.  The Stargate-produced song follows “You Da One” and the Calvin Harris-assisted “We Found Love,” which spent eight weeks at No. 1 and returns to the #1 spot this week for a totalling nine weeks.
