While Google's fledgling music service is pretty good, it's still far from perfect. Most GMusic users could probably jot down a laundry list of issues with both the app and service at a moment's notice; however, Google's slowly-but-surely doing its part to correct some of those problems. Let's take today's Play Music app update for example.

v4.5.910I

* Instant mixes continue playing beyond 25 songs.

* Added ability to shuffle an album, artist or playlist.

* New default album art.

* Previous button added to widget.

* Pinning progress now shown on album and playlist pages.

* Fix for the Galaxy S3 freezing issue.

It's a shortlist of fixes, no doubt, but it's a useful list. A previous button on the widget? It's about freakin' time. Longer instant mixes? Good stuff. Improved shuffle? Great – because everyone gets sick of listening to the same songs in the same order all the time. New album art and pinning progress actually displayed within the app? Both nice additions. And, for Galaxy S III owners, the app shouldn't freeze any more. That could be the biggest fix of the bunch, really.

Anyway, the app update is in the Play Store now, so you should be able to pull it on down.
