Thank you for the read new mystic!  This meter is tough.  Yes I will sing it to an audience if it works out.  It's funny because sonnets are a standard form but not for modern music.  If you make music and want to play live you have no choice but to promote yourself, unless you're in a band then you promote the band.  So it really makes me sick, I don't wanna do it, but the pressures are there.  So the volta is supposed to be me buckling and saying 'fine I'll do it!'  And it's a topic that I've never written about so wanted to, naturally.  I will make some edits of your suggestions.  Thanks again!

Self promotion makes me want to puke. -----> strong visual opening, also the word "puke" sets a down-to-earth informal tone
A necessary notion but disgrace-------> I think it would be stronger if it read "a necessary notion of disgrace"
in case egos shun sharing, saving face-------->not sure what this line is trying to say. it feels confusing based on what came before.
emaciates emotions each rebuke.--------->because the previous line lost me, so did this one. but I like the sound of "emaciates emotions"
A fluke of creativity entails
that sales of quality's just blowing smoke.---------> I *think* you're saying that art as business is a necessary evil. am I right? "quality sales" 
might make more sense.

Provoking folks won't remedy what's broke.---------->feels disconnected. who is doing the provoking and what is it?
The joke is insecurity prevails.-------->I like it, but I need to know the context behind it a bit
I'll spell in cursive if you think it's lame,-------------------->I like that the artist is being rebellious
anointing all my lines with genius' stamp,----------> I feel the sarcasm
and trample foes who want to hog the lamp,------------->are the foes the competition that is hogging the spotlight?
then cramp their style in a shameless frame.-------------->sounds like the artist is purposefully abandoning artistic form. am I right?
Proclaim: "you came to play the game of fame--------------->who is proclaiming? the artist? or is the reader supposed to proclaim it?
and tame the flame that shames all names the same!"

I like where this is going. it feels like a sarcastic jab both at critics and competition for regulating form. but it feels a bit incoherent and so I can't exactly determine the subject(s) being addressed throughout. but it did evoke a feeling of sarcastic rebellion. I think it's okay to rebel against form sometimes, but certain rules may still need to be followed to preserve coherency and just so it isn't being abandoned for the sake of being "different".
