I must say, I'm so glad to hear this is going in to effect! I've always been bothered by mixing on albums like Rush's Vapour Trails (Or RHCP's I'm With You, or every metal album ever), where it's so loud it actually clips in some spots! Beneath is a fantastic album but my ears would always fatigue long before the album was over. Now I'll finally be able to get through new albums again!
Although I do wonder if the iTunes radio thing would force bands to re-master their songs that have already been released? That would be very expensive and I have a feeling there would be enough of a revolt that it might be revoked...
Anywho, what do you guys think?
