How can I stop Apple Music from adding songs automatically?

I am new to Apple Music so please go easy on me. :) I have playlists on my phone that I'm pretty selective of what's on there. But after signing up with Apple Music, I have noticed that there are songs being placed on my playlists that 1) I've never listened to 2) I don't want on there. I manually remove them from my library when they show up, and if they still remain, I go through and swipe them to delete them. But when I go back into that playlist again, they are still there. It's almost like a virus that you can't get rid of. No back ups. No Shazam. I like some of the music that Apple suggests but as I said, I want to decide what is added to my playlists, not Apple doing it for me. Please help!!
