As someone who used the old app everyday. I am a HAPPYCAMPER! The old app was fine for its time, but so much has changed design-wise for android since then that it stuck out like a sort thumb. I am loving how fresh things look and how there are little clever transitions everywhere. Also having the Play store for music and the music app match makes them feel like a single seamless experience.
I also am liking the All access subscription, however, I did set myself a Google Now reminder to cancel in 29 days just in case I don’t forget to if I am not using it then. I almost feel stumped as to what I want to listen to know that the entire play music store is my oyster.
