Default Stop music when using Google voice typing

I use the voice to text button on the keyboard so I can speak text messages. I'm not sure when it started, but lately, when I press the voice to text button to start dictating a text message, the music that was playing in the background no longer stops.
It use to be that the music playing in the background would stop whenever I press the button so that I could dictate a text. It no longer does this. Am I missing a simple setting or something?
