My take on this is that if one wants an honest critical review of one’s song they should state something like construction criticism is welcomed. Otherwise I considered the song finished.

Also with the RDs, RTs and good sounding MIDI sources it is getting harder and harder to produce a ‘bad’ song. A good vocalist and/or instrumentalist can produce some outstanding music now with BiaB/RB.

As far as a song being monotonous, if that was a criterion contemporary radio airplay would be dead! Many top hits of both today and yesterday are/were redundant.

Broadjam has a rating system very similar to what you describe and personally I don't think it works. One of our PSR (a band I help record and play with) members has sent songs up on Broadjam and the ratings are dependent on what music genre is being evaluated and by what music genre the one who is rating plays. For instant he put up a country song and got a couple of very rude and bad ratings. Things like “this sucks” and “this is crap” came up with a 1-2 out of 10 rating. When he looked at the evaluators he found out they were gangster rappers! He also got some 10 ratings, of course from country musicians.

Although you did bring up some good points I like the ratings as they are now. However if one wants he music to be evaluated he should say so.

Finally I personally will not say a person’s song sucks. I know that they put in a lot of time and effort to produce that song. Constructive criticism I will give if asked for or if I feel it is necessary but most of the songs here are very well produced.

This is just my opinion on this topic and I’m sure others will disagree.

Doc-take it easy John this is just a sharp scalpel. It will not cut deep so don't worry.
Me-I'm not John
Doc-I know, I am!
