Putting a soundgoodizer on the master bus is like trying to force everyone to play soccer no matter how much they suck at it.
Basically, all your instruments have their own personality, and by doing almost anything significant across the entire track (like soundgoodizer, which is basically 4 Maximus presets), you will favor certain instruments and destroy the others. All instruments require their own EQ, delay, compression, sometimes even reverb (reverb, however, often works better if you can consolidate it to groups, since that's more realistic). Each one has to be treated carefully so that it's presence and feeling can be fully expressed in the mix. Everything done on the master bus should be done extremely carefully, and in general should be really subtle.
Using Soundgoodizer at all usually isn't recommended in a final mix. It's really handy for drop in fixes when you want to focus on fleshing out an idea instead of poking at an equalizer for 15 minutes, but it should almost always be replaced by something else because, again, its basically 4 maximus presets except you can't change any of the values. It strips away your ability to tweak things. If you don't know *how* to do those things, then its use is more acceptable, but you should try to learn how. If you go into Maximus and look for the "Soundgoodizer" presets, you can actually look at exactly what it's doing, which is a good start.
As for your song, I'd love to listen to it to tell you what's going on, but according to soundcloud, you have no publically available tracks, so i'm guessing you made it private, and thus no one can listen to it. I'm going to go ahead and guess that either you put too much bass in the track and it ate up all your headroom, or your instrument choices have conflicting frequencies and there's two or three choke points that are crushing everything else by improperly triggering the compressors.
