Default Google search update breaking dictation on my Nexus 5

I have a nexus 5 32 gigabyte. I Drive for a living and so I pretty much exclusively use dictation to input text from my phone, as I am doing now. The new Google search update makes it so when I'm playing media and I hit the dictation key it does not pause the playing media. This has caused me to uninstall updates so I'm missing out on some of the cool new Google now features like knowing where I parked and even things as old as being able to set a reminder with voice commands. is there anything I can do to fix this? Or do I just have to wait for the next update? Any help is appreciated. I'm sorry if this is in the wrong forum.
