Greg most of us here are mature adults and write adult music so it is hardly surprising that few of us write or even understand kids chart music and even less could give a decent crit on it. I would not consider a critique from a kid who writes like Justin Bieber would be much good or appropriate for my style of music either. So it is mutual.
I doubt very much if a couple of five minute video reviews or pro critiques could help anybody that much and the chance of being picked up with a record deal by some top professional is just a carrot to lure people in....it is unlikely to happen. There is no shortcut to learning the craft and attaining success is a combinataion of luck, hard work and contacts.....
But if Blazetrak works for you then I do not have a prob with that.
You obviously have your finger on the pulse and know better....keep us posted if anything ever comes from your dealings with Blaztrak....I would be genuinely interested and a trifle surprised if it ammounts to much. That said nothing would suprise me about the music scene of today. Some real stinkers have made it big.
