I would not mind something like that and would definitely offer constructive criticism to all artists.

One thing that I found lacking when looking for sites that sell music, is I could not find a site where you could attempt to sell your Lyrics, or songs in unrecorded format. I can't write music, but I do attempt to write song Lyrics. There were one or two sites but they wanted you to pay hundreds of dollars to access their services, and there was no way of knowing if they were even legitimate. I would like a site where you can sell Lyrics not just recordings, and not have to pay to do it.
Just wondering, if you guys are still working on the song ... or have lost interest ... just have not heard anything.
