What to do to get exposure?

 So there is a rumored New Zelda game coming out soon. 

The title is in speculation but that doesn't seem to stop all the people who want to get their name out on the music that isn't even in the game but will trick people into thinking it is game music.

So has instrumenal music become worthless? 

Because people are doing this, is the following true?

1. Instrumental music = good but nothing special
2. Instrumental music that passes itself off as the 'leaked" music for the game. = Ill Iisten to it but it is nothing special
3. Instrumental music in the game = The real deal.

Is every bit of exposure good? Or do you have to get a legitimate position to get the proper kind exposure?
