David, this is a catch 22 situation. In essence you are asking for a "Casual Review Showcase" and a "Critical Review Showcase". This is a good idea but could lead to difficulties. I have seen wars break out over "critical" reviews on other sites; one must have very tough skin when posting a song for criticisms.

Plus who does the critical reviews? How would a jazz musician give a critical review of an ambient song? It could get very difficult. There are other sites that can evaluate your songs, Taxi is one. There pros can do the evaluations.

I have seen a number of constructive criticisms welcomed on the current showcase forum. As I have said before all of my posts are open for constructive criticisms.

I can see both sides of the issue on this suggestion.
