J.U.S.T.I.C.E. League is an American record production team composed of producers and instrumentalists from Tampa, Florida.

The Breakthrough is the seventh studio album by American singer Mary J. Blige. It was released by Geffen Records on December 20, 2005. Initially expected to be released in 2006, it switched release dates with Blige's first greatest hits album Reflections (2006) after fruitful collaborations with a host of songwriters and record producers, including 9th Wonder, Rodney Jerkins, Jimmy Jam and Terry Lewis, Bryan-Michael Cox, J.U.S.T.I.C.E. League, Raphael Saadiq, Chucky Thompson, Cool & Dre, Ron Fair, and will.i.am, prompted Blige and her label to shift material from Reflections to The Breakthrough.
