Great article by Kirk McElhearn, although I don’t agree with his conclusion:

On the other hand, Apple is clearly saying that overly loud music doesn’t have a place on iTunes Radio.

I don’t mind Apple using Sound Check for iTunes Radio and I don’t see it as a statement by Apple about loud music. It’s just a way to normalize the volume of many different songs to give the user a more enjoyable listening experience.

I do wish music producers would lower the volume on their music—give it some room to breathe.
