I switched from a iphone to the Samsung S5. Got all my music converted over no problem. I have noticed that it went into both the google music and the samsung music. What I can't find how to do is sync between the two. I bought a song on google and I know no big deal listen to it on google. I like to listen to my music a lot in my car while a travel. I like being able to use the S voice to find my song and play it so I don't have to scroll thru while driving. What I have find is that anything I buy in google it can not find only songs that are in the samsung music app. I have tried everything I can think of so now I'm asking for help?????
