There is no reason that you can't do what you are describing - in the Showcase.

Simply start your post by stating that you want critiques. You can even say something to the affect of "hard critiques" - with whatever aspect you are wanting feedback on. The subject line could have some type notice, too... "Critiques Wanted: My New Song"... I'm sure you would get some feedback from all sides...

And... you can take those comments/suggestions with a grain of salt if you choose. I have had critiques of song lyric and structure (in the Showcase) that were some of the most ridiculous song suggestions I've ever heard...


And, you can let folks know - in the Showcase - that you think there is some aspect of a production that could use "a tweak" - if done in a respectable, polite manner. (I remixed a song recently based on comments about an odd sounding harmony).



(I think we have too many separate sections on this forum as it is... just a personal observation, of course)
