Voice action cannot find my application

I am trying to add voice action to mine music app. When I do a voice action and say:

Play Someone like you

Google voice search recognized that this is a song and it allows the user to choose which applications should open this intention (including my application). When I clicked on my application, I got the name sony, as expected.

I noticed that I can say:

Play Someone like youonGoogle Music

This will allow Google voice search to open Google Music directly, after a short timeout.

= - = - =

So, what does not work, I can not use Play [Music] on [My App]; this will give me google search result.

, , - , Play [Music] on [My App] ?
