But really, EQ wasn't designed to do "post production" of your music. It's there to compensate for your listening environment's unique acoustic characteristics.

Yes, and we all live in a perfect world with flowers and little fluffy bunnies everywhere.

The truth is that there are some masterings that, when placed into a shuffle with other recordings, need to be EQ-corrected. They were simply botched in the mastering phase and sound awful without correction.

I guess EQ's per song is a good thing to have, but who wants to spend that much time EQing their entire collection?

We're not talking about EQ'ing one's entire collection. The "need correction" albums to which I'm referring are quite few in number. Out of my entire collection, I could probably count them on one hand.

An example is my remastered copy of The Fixx's "Shuttered Room". This is an album that I owned on cassette tape in the 80's and I just loved it. It was stolen (along with all my other cassette tapes) when my first stereo was ripped off a few years ago. I tried to order it on CD a while back and discovered that the original pressing was out of print. Amazon had a copy of the "remastered" pressing available. I noticed that one of the Amazon reviewers said that the remaster was over-brightened, which was why I wanted the original instead of the remaster. They were dead right, this remaster is downright strident compared to all of my other albums. They really butchered it in the remaster.

My dream is that I could group-select the songs from "Shuttered Room" in Emplode and say "Use EQ preset number 7 for these songs". For the other songs on the player, it would continue to use the current default EQ setting.

I could dial back the bass on Madonna's "Ray of Light" a little bit. Not much, just a tad. I could take some spoken-word recordings and adjust their EQ's more appropriately. Overall, I wouldn't correct very many tracks with it, but the few things I would correct would be awesome.

EQ is supposed to be a "set and forget" thing, and all of the crappy head units that offer "Jazz" "Classical" "Rock" EQ's are a solution looking for a problem, if you ask me.

I agree with that statement. Trying to apply EQ-by-genre is totally missing the point of EQ. I just retch every time I see one of the "Jazz, Classical, Rock" things on a car stereo. The person who invented that should be given a nice hard dope-slap.
