Oh GOD no Cry Me Out

He voice coach just said 'shout it out as loud as you can and put as much vibrato in your voice as you can get away with ergo people will think you are a top singer.
Now I know Pink, beyonce and the rest in the list above are NOt the best pop stars in the world, by far, but they are competing for roughly the same listeners, and there is NO comparison with those lot compared to Pixie Lott. I have no great love for Beyonce, Lily Allen or Katy Perry at all, but they have far, far more talent than PL.
PLEASE don't think I drive down the street listening to katy Perry and singing along (my dd would kill me for a start!)
