Playing specific iTunes songs on Apple Music with Alexa

I have been listening to my iTunes through my iPhone onto my car stereo. I have now subscribed to Apple Music and need help in getting Alexa to respond to requesting songs on iTunes. I can be listening to iTunes music and decide that there is an individual song from iTunes I want to listen to. When I do this, Apple Music will play the song, but will also include the entire album. Do I say Alexa play a certain song from iTunes. Just not sure how this works. All help would be appreciated.
