Drake posts Back to Back diss track to answer Meek Mill

Award-winning rapper Drake has responded musically in an ongoing feud with Meek Mill, just as the Philadelphia rapper was greeted with loud boos in the Canadian performer's hometown.

Over the past few days, Drake has premiered several new songs online via the audio-sharing site Soundcloud, including a pair of so-called "diss" tracks: the low-key Charged Up and harder-edged Back to Back Freestyle.

In Charged Up, the Toronto-born, Grammy- and Juno-winning rapper slyly references the simmering feud by noting he was "done doing favours for people, 'cuz it ain't like I need the money for doing features."

In the othertune, Drake raps: "This is for y'all that think I don't write enough. They just mad 'cuz I got the Midas touch."

He continues with a more pointed dig at Mill, on tour as one of the opening acts for his romantic partner, Nicki Minaj.

"You love her then you gotta give the world to her. Is that a world tour or your girl's tour? I know that you gotta be a thug for her. This ain't what she meant when she told you to open up more."
