How to get Siri to play songs in my library?

Last night I was driving home and said "hey siri, play metric". Metric is a local band and I have one of their albums on my iPhone. Siri responded by subscribing me to Apple Music and playing the songs from there. I have noticed similar things in the past. I will ask it to play an artist or album that I have on my phone, and it previously would tell me I don't have Apple Music and would not play it. Is there some way to turn this off, or some magic phrase I can use to tell it to look only in my local library? I do not have Apple Music and will never subscribe, I simply want to listen to the (large amount) of music I already have.
