Cached music can now be handled on external storage
There's a new update for Google Play Music rolling out from today, and it brings a pretty big feature addition for anyone using Google's music app on a device with an SD card. The new Google Play Music version 5.3 introduces the ability to store cached or pinned music on external storage — i.e. a microSD card — as an alternative to internal storage. The app has always been able to play music from external storage, but until now cached music from online libraries was limited to internal storage.
It's a pretty big deal for the many users of Android phones with an SD card slot but limited built-in storage, for instance most Samsung phones and lower-end devices from other manufacturers. Cached music can quickly chew through precious internal storage, and so offloading it to an SD card wherever possible makes a lot of sense. It's a curious decision, however, given Google's stance on SD cards, and the lack of external storage on current Nexus devices.
As usual, the new version of Google Play Music is being pushed out to devices gradually as part of a staged rollout, so watch out for it in the days ahead. The new option to change your cache location can be found under Music settings > Download > Storage location.
