It’s a really great option for those that are in the Google-sphere.Keith I Myers – 2015-06-23 12:58:17-0400+Joseph Cappellino – Essentially however there are some benefits as you can still upload 50,000 of your own songs and stream those without commercials. Santos Chavez – 2015-06-23 16:03:57-0400That is awesome! I knew T-Mobile had Music Freedom, but I had no idea Google Play Music was in the list!! Dang, it’s making it reaaallllyyy tempting to switch to them from MetroPCS, especially now that GPM has a free version :3
