I think Lightspeed is her best bet out of the songs that we've heard so far. I mean, I've never listened to the song, () but from what I can tell it would fit right in with what radio is playing.
She better release Lightspeed or Breathe if she wants to do anything other than flop. In My Trunk, despite it's great verses, is forgettable, senseless, and even annoying at times, mostly due to the awful chorus.
