by Dec 20, 2013, 3:49 pm It did not begin its run as a monster, but Lea Michele’s “Cannonball” definitely impressed within the context of the “Glee” universe. And thanks to that impressive opening week, Michele becomes the first “Glee” cast member to land on Billboard’s Hot 100 as a solo artist. Written by Sia, Benny Blanco and Stargate, “Cannonball” moved 51,000 digital copies in its first week to rank at number 22 on the Billboard Digital Songs chart and number 75 on the Hot 100. While “Cannonball” represents Lea Michele’s first big music move outside of the “Glee” walls, it would be impossible not to compare its performance against recent “Glee” releases.
