I'll just chime in with my 2 cents and agree with what's already been said. Up until a few months ago I was looking for an EQ formula that would work with everything and now realize that no such thing exists. You have to know your music, some tracks sound awesome gradually mixed in while others sound awesome dropped straight in. It all depends. One thing that I'm getting into that has made worlds of difference in my mixing satisfaction is harmonic mixing. Everything that I've mixed harmonically sounds worlds better than my mixes usually sound and has made mixing way more enjoyable.
