No problems for me
I use Google Music on a 5th gen iPod Touch as well as my Samsung Galaxy S6 with data and/or wifi and its always worked for me, Ive never had a problem with Google Music. Now that Im a mom, I use Google Music for my baby daughter whether we are in the backyard or in a crazy Walmart during Christmas rush, its pretty great and also great if you like to be introduced to all sorts of new artists solely based on channels or stations playing genres versus airtime-type "popular" music, but it has that, too!
