Google’s efforts in music have had a number of names before arriving at Play Music in March 2012. The online service consists of a cloud locker, streaming service, and podcast directory. As of February 2015, Google bumped the number of songs users can freely upload from 20,000 to 50,000. Those songs are downloadable and listenable from Android and iOS, as well as a web app.
All Access is a $9.99 per month streaming service that gives users access to 35 millions songs and countless radio channels and playlists. As of 2015, it is available in 63 countries and sold in conjunction with YouTube Red in some regions. Most recently, Play Music added support for podcasts subscribing and listening.
