A very simple check is to capture the form submit and check the string from input :

$("form").submit(function(){
   
   var genero = $("#genero_post").val().toLowerCase().trim();
   
   if(genero == "brazilian music"){
      console.log("Ops!");
      return false;
   }
   
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><form><inputid="genero_post" type="text" value="Brazilian Music">
   <br>
   <button>Enviar</button>
</form>

If the string is " brazilian music " (not case sensitive), the form is not sent ( return false ).

If you want to check if the string " Brazilian Music " is not case sensitive, you can use the .test() :

$("form").submit(function(){
   
   var genero = $("#genero_post").val().toLowerCase();
   
   if(/brazilian music/.test(genero)){
      console.log("Ops!");
      return false;
   }
   
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><form><inputid="genero_post" type="text" value="Brazilian Music 123">
   <br>
   <button>Enviar</button>
</form>

If you want to check multiple terms, separate them with a vertical bar | :
/termo 1|termo 2|termo 3/.test(genero)
But if there are many terms, I would suggest using an array.
