Is there a 3rd party app. that I can download to play iTunes on my Galaxy S5?
I have used doubleTwist for a few years. Syncs iTunes playlists with no issues. The app itself (doubleTwist Play Music/Podcast - Android Apps on Google Play) is free, and syncs with your data cable. There is an app (AirSync iTunes Sync & AirPlay - Android Apps on Google Play) that gives doubleTwist the ability to sync wirelessly. I think it costs about $5 (or it used to). Works great.
Thank-you, I will give double twist play a try!
