How could I make Siri listening the music immediately without asking?

I saw some Siri demo on YouTube shows that when you enable Siri by holding the home button, Siri will listen to you and if it recognised that the background is a song, a music icon will appear and then Siri will tell you what song it is. I tried my and it won't work. I have to ask Siri " what song is playing" everytime and Siri will start listening.

Just today I, too, was wondering why they removed this 'feature' from the final build. Sometimes you have only a second to spare and simply activating Siri and it recognizing music is optimal. It wasn't as it is now in the betas, and I hope they change it back. It worked well, too, so I don't know why they changed it.
