I just got a Droid Turbo 2 and I'm trying to transfer my music to it, but I can't figure out how to get my music I've downloaded on iTunes to show up in Google Play Music. This was never a problem on either my HTC One M8 nor the LG G4 I had right before getting the Droid. When I go to transfer the files, it does the whole thing of asking me if I want to be able to play or copy them, and I select yes, play on this device and do this for all files and it looks like it's loading but then the files aren't in the Play Music app.

I like your name! And thank you, I actually ended up converting all the files to mp3 (they were mp4 or something before) and they finally transferred properly.
