Thing is, it's easy to knock some of these music types you don't like very much... It's an altogether different thing to actually try to play it!
For those of you that think there's nothing much in an Ashlee Simpson track, I suggest trying to make one JUST like it. For a start off, if you succeed, you will make a boatload of money

And if you don't, you might have a little more respect for those who can

I'm not saying you have to LIKE the stuff, but even stuff you don't, at the chart level, has a LOT more in it than most here are willing to admit...
