I hesitate to be the one to answer as I am not the one who can best give this justice... but just for one (not a full composite of what MusicMatrix offers) ; It is the only website on the internet that offers unique artist content (i.e. maino's upcoming video promotion) with the ability to edit it and compete for prizes.
Do your DD and it will be obvious. If you don't like what you see, don't buy in. Our party will still be held. Good luck in finding something else to invest in. GO ENTI!!!
